Vw beetle 1600 oil pressure

Much of that comes down to the simplicity of the air-cooled engine's design; but simplicity can be a double-edged sword when it comes to maintenance items like oil. VW was very proud of its engine's anywhere-anytime reputation, and its popularity all over the world. Beetles were designed to be run through the snow on sawdust and moose urine; maybe that's why the VW owner's manual said of oil changes: "The VW engine makes no demands in respect of engine oil quality, which cannot be fulfilled by every well known and popular brand.

Also not mentioned by VW is the fact that these engines, which lack an oil filter, require changes every 3, miles religiously. From negative 4 degrees Fahrenheit to 77 degrees, a 10W or 10W will suffice. If you never drop below 0 degrees, you can use a 15W or 15W, and 20W or 20W will suffice if temps don't drop below 14 degrees Fahrenheit.

These air-cooled engines tend to run hot, so don't use anything thinner than a multigrade. You can use an old single viscosity oil like an SAE 20, 30, 40 or 50, but it'll only narrow the oil's operational range.

The fact that the air-cooled engine lacks an oil filter really affects your engine oil choice. First, you'll need to use a "high detergent" oil that will keep sludge and soot suspended in the oil, and keep it from sticking to the inside of the engine.

Some people prefer a heavy-duty diesel truck oil like Rotella T because it has very aggressive detergent packages that will keep the engine clean and happy, but a standard high-detergent automotive oil will suffice. If you're switching from standard to high-detergent oil, mix it half-and-half on the first oil change; you don't want all the sludge dissolving and breaking loose on one oil change. Don't bother with a synthetic. You have to change the oil every 3, miles to get rid of dissolved sludge, so the synthetic's ability to run 6, miles or more is wasted.

Four required per car. For installing small hole oil cooler on large hole case, or doghouse cooler stand to small hole case. Note: 26 mm gears provide more moderate and desirable oil pressure than 30mm Aluminum housings and steel alloy gears make for superior performance.

The aluminum housing expands and contracts with heat fluctuations at the same rate as the engine case so the possibility of leakage is minimal. It seals the tube to the engine breast plate. It keeps dust from getting into the oil. Includes a system of internal baffles that separate the oil from the air, then returns the oil back to the engine.

With Audirac Racing's innovative oil pressure valve body, VW engine oil pressure is instantly stabilized! This wear eventually allows oil to flow around it, "an internal oil leak", causing low oil pressure issues that are common with vintage VWs. Our Oil Check Valve Kit includes a valve body that sits firmly in place. The metal marble is what moves against the spring instead and completely seals up against the valve body.

This allows oil to stay within the system until it reaches the ideal oil pressure lbs, 70lbs MAX which at this point allows oil to flow without compromising oil pressure output.

On dual relief cases, installation involves only replacing the stock oil pressure relief valve on the pully side and leaving the oil pressure control valve on the flywheel side alone. When we rebuild cases inhouse, we eliminate the oil pressure control valve on the flywheel side entirely and drill a new relief hole on the pully side. Adrian at Headflow Masters has installed this setup in all of his engines, new and old since he first opened his shop. The funny thing is, it works so well that his clients don't return for years because their engines last sooo long!

If your engine and its parts are in well working order, but you have oil pressure issues, there is a very high probability that this Kit will fix your problem immediately. Other oil pressure booster kits are just a variation of the stock plunger We believe they simply just use stronger springs which does not fix the problem. If the crankshaft pully is loose when tugged on, the case most likely needs to be rebuilt. Thank you.

Wipe everything down and then come back after a few minutes to see where the oil is dripping from. Another place where you can see drip is near the rear main seal under the car. If that happens, you need to get a circular seal.

VW Oil Pressure Fix

You need to take out your engine, the clutch, the pressure plate and the fly wheel and you replace the main seal. It might be hard to do this at first, but you will need a 36mm heavy duty socket in order to remove the fly wheel. You will need a tool that keeps the fly wheel in place. Pushrod tubes can also lead to a Beetle oil leak. They do sell kits that allow you to avoid removing the engine in order to replace the pushrod tubes, but the main idea is to do it the old fashioned way.

The oil cooler can also leak and you should also pull the engine in order to replace the cooler. The issue does appear when you overuse the engine. In order to remove the cooler you will have to remove a nut and then you will have to see if there are leaks or not.

If it leaks, on the down side of the pushrod tubes you will see oil leaks. The valve cover gaskets might be leaking too, so you need to pull them down. Use an old rag, slip it in the hole and pull it, as that will help you pull the valve cover without a problem. Usually, these are the area where you have to fix the VW Beetle oil leak. Remember to try and fix oil leak problems fast, as otherwise you will end up with quite a bit of issues in the long run. Your email address will not be published.

Table of contents Spot the oil leaks Fix the oil leaks as soon as possible. Tags: restore vw beetlerestore vw bugvw beetlevw bug.By andrew s Date Edited We have some great temps in CT. Deffinatly have sping fever now!!! My buggy ran great. Real joy to ride after all the work done but i am questioning the oil pressure.

I put all new electric VDO gauges in including a oil pressure gage and a idiot red lite if pressure drops below whatever the sensor says is not enough vdo sensor too My Allison has a sinle port engine with single carb and is not built very much if at all Last year i had new balanced pistons, rings, sleeves,and piston arms put in so i fugured all was good.

They said the rest was fine and i left it at that. Runs real nice. Right now it has fresh oil it in. My mechanic just changed it with i think or something He has been a mechanic for 40 years and i am sure he knows what is what.

I thought we should use but he said in the south but not in ct. Anyways the gauge always read higher when first running till it warms up and with a few RPM's we are looking at 30 psi or so. When cold at idle it is 20 psi or so Once it warms up with a few RPMs going it drops to say 20 psi or so and at an idle down to psi and then at about 5 psi with idle the red lite comes on.

My question is should light come on? Hey not sure this is normal or not but now that i have a good gage that works well i think it does just want to make sure i do not starve this engine and to be honest with you i do not want to see the lite come on every time i stop!

Thanks Andy. By ManxBug Date But we only run the cars and buses in the summer. I've been told that they were designed for 20 50 in a German climate. Which is only a couple degrees warmer than where I live. By andrew s Date Just had to pull It out!! Kind of like summertime in Canada??Crankcase Ventilation.

Rob wrote - There is an opening into the crankcase around the pulley shaft which is designed to pull in fresh unfiltered! If you remove the engine pulley you'll see a couple of annular slots in the case around the shaft. The shaft itself has a spiral groove cut in it, so it "screws" air into the crankcase.

This ensures that there is always a slight overpressure in the crankcase, which, combined with the slight vacuum in the carburetor induction system, pulls oil fumes etc.

You might hear the beach buggy boys talk about "sand seals" and these are plug-like devices which seal off these slots so you don't get dust and sand into the sump. There is a large washer around the shaft just behind these slots to act as an oil splash plate, and since the air is being drawn into the crankcase, it encourages the oil there to dribble back into the case and sump, rather than force it's way out.

What is supposed to happen is that the crankcase pulls in a small amount of fresh air through the slots behind the crank pulley. There is a spiral groove on the crankshaft which 'pumps' air in through there.

Volkswagen Beetle OIL SYSTEM

This is deliberate, to create a positive pressure in the crankcase, which forces any burned gases leaking past the rings up through the breather and through the carby.

This way the oil gets less contamination from the cylinder gases, and any excess foaming of oil etc. But when you lift your foot -- close the throttle -- there's no low pressure to maintain air flow through the crankcase. If you've got a blow-by problem combustion gases getting past worn rings and valve guidesthe pressure inside the crankcase can be great enough to defeat the oil slinger, blowing a gust of oily vapor out the inlet where the pulley does a nice job of distributing it around the engine compartment.

If you're not using the standard air cleaner, you may not be getting enough vacuum to suck the oil laden fumes up through the alternator stand, resulting in the mist blowing out backwards through the ventilation slots behind the crankshaft pulley. Take a look -- any evidence of the oil streaking etc inside the cleaner would indicate that it's pulling the oily air through properly.

You MUST have the tube from the oil filler connected to the air cleaner, and have an aircleaner which develops a slight vacuum inside the filter element.

Many aftermarket air cleaners do not make any provision for fitting a vent line from the oil filler tower. And those that do have a connection may not develop sufficent vacuum, causing oil to come out of the crankcase where air is supposed to be going in. Clean everything up real well to spot the source. Try this: At idle, remove the oil filler cap and hold it loosely over the opening.

It should just flutter without really being blown away. If blown away, there is excessive blow-by. Rob responded - Three other possible sources of oil leakage into the engine compartment have been suggested -- the oil pressure switch, the dipstick, and the oil filler.

The oil pressure switch should NOT have a gasket or O-ring.There are 2 separate oil control mechanisms, the first is pressure control, which is done by the flywheel piston. When pressure is "excessive", the piston is forced down and oil pressure is relieved via a bypass port back to the sump. If you have a HUGE pump 30mm or largereven when the piston is down it still won't bypass enough oil because the relief port is too small.

So if you are careful you can increase the size if this relief port, but this is not necessary if you only use 26mm pumps like we do. Putting in a stiffer spring will increase the point at which the pressure will bypass. It will recover when the piston closes again. The cooler relief piston operates in a similar manner, but it senses the pressure drop across the cooler. If the oil is cold, there is a lot of pressure drop across the cooler cold oil is thick and tough to move.

If the pressure drop is small, "the oil must be hot", and the piston remains closed and routes as much oil as possible to the oil cooler. Oil pressure is NOT affected by the cooler relief system, it's sole responsibility is for sending the appropriate amount of oil to the stock oil cooler. If the cooler relief spring is replaced with a stiff one, the oil will be routed to the cooler before it gets warmed up, and the engine oil will have a tough time reaching operating temperature.
