Car Forum / Volkswagen / Water Cooled Volkswagen Cars / May 2007Oil pressure problem
Help, I need to know what the oil pressure specs are for my 95 Golf III GL 4 cyl 2.0 engine My idle reading is 8 and with the engine reving is 26. The oil pressure buzzer/light keeps going off intermitently usually when the engine is warm. I can get it to go off if I rev the engine. I have already changed both oil pressure sensors/switches. I'm guessing that I might need an oil pump? I have already tried using thicker oil to no avail. It only has 115,000 miles on it. Anyone out there that has had the same problem and solved it? > Help, I need to know what the oil pressure specs are for my 95 Golf > III GL 4 cyl 2.0 engine [quoted text clipped - 5 lines] > thicker oil to no avail.

You also should check the pressure relief valve (assuming that model has one) Past that you are doing to oil pump and serious engine wear.

As Joseph said, the first step is to check the pressure with a real mechanical gauge. You can probably buy one at Autozone for less than $30. Use some teflon tape on the US adaptor to minimize leaking. Maybe they have a real metric connector now. Or you might just bite the bullet and install a new pressure sensor (there may be two) on the chance that it will fix the problem. Anyway, if the pressure is low (especially when hot) the oil pump is probably worn out. This would be unusual in the 2.0 engine, I should think. Worn main bearings will also lower the oil pressure. Our 1982 rabbit had a low oil pressure problem years ago. I pulled the pan and found two of those foil seals that you peel off the top of an oil bottle clogging the screen on the oil pump. Unfortunately, much to my chagrin, I found out last weekend that you can't pull the pan off a 2.0 unless you pull the transmission first, because some of the pan bolts are blocked by the bellhousing. I was going to replace the main crankshaft seal using the old "2x4 jammed into the crankcase trick" to remove the crank bolt, but it looks like I'm going to have to build a tool to hold the crank. :-( Bill 78 Rabbit...10/77 - 4/02 82 Convertibles(s)...since 93 95 Golf GL...since 11/99 07 Passat 2.0T 06 GTI DSG Take out the CAT to reply by email Hmmm I removed and installed a pan off of a 1995 Jetta 2.0 auto. Yeah it had a few bolts that were hard to get to and almost hidden by the auto trans but they definitely were doable without removing the trans. I think I needed a 1/4" drive socket set with a flexible extension. I really forgot what I used! <g> I had to remove the Jetta's pan since it had lost a battle with a parking curb. Dented the pan and cracked the oil pump plastic windage tray which broke into pieces and clogged up the oil pump screen..... = .....low oil pressure. Some people remove that crank sprocket bolt by securing a socket and breaker bar with a cheater bar to the ground and then crank over the engine slightly. This is usually enough to loosen that bolt. Now putting it on is another matter. Some will secure a tie-down strap to the sprocket and some sturdy piece of metal on the car like the right side control arm. Then carefully torque it down tight and I do mean tighten it down! I have replaced a few crank sprockets that were destroyed by not being on tight enough.

I couldn't even tell how many bolts were up there so I looked at the new gasket that I bought (wasted money :-( and it looked like there were three bolts in the blocked area. Maybe the manual trans bellhousing is more "obstructive" than the automatic's. Assuming I could get at them, I guess I'd have to buy a flex torx drive to do the job (do they make such a tool?). In any event, the job (crank oil seal) is done. I cut, filed and drilled a 16 inch piece of 3/16" tempered aluminum that I used to replace the "four bolt" crank pulley and was able to loosen the crank bolt with no problem. Torquing the new bolt was a bear. Actually, torquing the bolt to 66 ft-lbs was easy but to get that additional 90 degrees, I had to go to work and borrow and old piece of pipe to put over the 1/2 inch drive flex handle. The bolt screamed in agony (despite pre-oiling) and I finally got about 80 degrees before I gave up. Next time I'll use anti-sieze on the bolt shoulder (if there is a next time!). But thanks for your reply!

But in this case Bentley specified that the crankshaft bolt shoulder and threads should be oiled. Bill I think the manual trans should have a little removable flywheel cover bolted to the trans, at least the 92 Golfs did. Maybe it is hiding those oil pan bolts. ;-) > Well, I'll look again, Dave, but the bolts looked completely covered. > I couldn't even tell how many bolts were up there so I looked at the new [quoted text clipped - 3 lines] > them, I guess I'd have to buy a flex torx drive to do the job (do they > make such a tool?). > I think the manual trans should have a little removable flywheel cover > bolted to the trans, at least the 92 Golfs did.

I've got to get back under it this weekend (getting it all fixed up to sell it to a friend (*sniff*)... I hate to see that car go. It's been the best car I've ever owned and I've owned cars for 42 years. It seems logical that VW would provide some means for removing the pan without having to pull the transmission.

No, I got the crank oil seal installed without having to "remove" the pan :-) |
