damned electrical bugs.

Ok, had oil changed yesterday, oil light keeps flashing. Goes off when I push clutch in and rev up. I cannot find it, but it sticks in my mind that using too thin oil could do this. Car is running great, I change the oil and this crap starts again. Maybe add motor honey or something to thicken it up?

God, why couldnt I be good with a set of tools? lol


Thanks again..

Stay safe, stay well. Jimmy.

What type of oil are you using?  Checking oil pressure with a mechanical gauge couldn't hurt either.

I have had this wierd issue on my 85 jetta and did all sorts of stuff to try and help because the low pressure alarm would go off.   This persisted after putting another engine in as well.  Taking a manual reading from the head I would go over 100 on cold start and pressure is always in spec(except in some high speed sweeping turns?).

If the tach is working then I assume the alt belt isn't slipping so I don't think that is an issue.  My cluster seems to work for everything else but at the end of the day I am assuming that has something to do with it.  I have tried replacing the sensor a couple times.  Also seems like sometimes its ok and then during other sessions it gets real pissed off.

This kind of thing scares me on these old cars so now I have 3 auber electric gages.  water temp, oil pressure and egt/boost.  you can set warning levels and i have some aircraft buzzer that they will trigger if those are met.  annoying noise that would freak out first time user.  But I have had family borrow this car and blow up engine after seeing flashing temp gage so it is what it is

What kind of filter is on there? Some VWs are sensitive to this, if it's not Mann or Mahle the oil warning system acts up.

I grabbed a Mobil 1 " extended performance" or something like that oil filter. A little larger than the one it replaced. But even with oil level at full, it could cause this? You know I don't (and can't...lol) doubt you guys, but a little quirk like that? Crazy...

Don't have a tach, so thats out. lol. Engine has 11k on it rebuilt and installed by a member on here. All seems fine. Once oil was changed coming back from shop light was flashing and buzzer went off. Pushing in clutch and revving engine stops it for a while, but it is almost non stop. I'm looking to drive this on an 8,000 mile 2 (possibly 3) country trip. Drove home from Brooklyn this mornning after a 24 and np till I started stop and go local traffic. I'm just wondering if I should add motor honey or something to thicken it up. For the life of I can recall possibly seeing it posted on here, but I am probably wrong. Or find the STP or Mahle filter JC suggested..

Thanks for the replies, my friends.

these engines are VERY picky about having the correct oil filter..

FRAM should NEVER come NEAR your VW..

I was aware of Fram filters, I do avoid them. But even after being on this site for years, you learn something new every day. I lost my first VW diesel to a Sears oil filter, and try to stick with name brands. No problems with an STP S3569 filter for 3400 miles (too many hours working, but I know oil change is vital). Guess that little bit more pressure for the Mobil 1 obviously makes a difference. Never knew.  You guys are THE BEST.  Just keep ur phones handy in case I need help on my trip....

I would definately bank on the filter, but just in case it wouldn't hurt to throw a gauge on it and see what it is actually doing.

Have a gauge on a cluster, not hooked up. I had this problem once before with old engine, and my nephew installed it. According to Scott, when he tapped it in he stripped some threads and screwed the head up (Scott obviously knows more detail).  After the last setup with the 'guru' found on TDIForum, the car runs great. Needed new struts/shocks, tie rods, ball joints, and other minor things. And with the new stuff Scott added (engine, radiator, water pump and tons of other stuff), I am very confident this car will make the trip no problem. It's just these little bugs that annoy me, just wish I could fix the damn car myself .  But with you guys, at least the issues are narrowed down considerably.

<-----big enough dick to ask.... you positive you did not UNPLUG a sensor on oil filter housing??? that will do it... also 82-~current have dynamic oil pressure.. 1 bad sensor amd light/sound right now... make sure they plugged in..

Not being a dick, trust me. Car was on lift, filter removed and replaced. I can take a peek and look for sensors. Genral location in vicinity of filter? Thanks.

I used to be on the fram hating boat, but have you opened one up recently? They upped their game significantly. They do not use a rubber diaphragm for the by-pass anymore.. its a metal spring loaded type, just like Mann and other reputable German filters.

If the filter were the problem, this engine would have been toast by now with no oil pressure.

Again, ya learn something new every day. I'll find another S3569 at a pep boys or something, then order a few Mahle filter from GAS or similar. Looks like its staying home, I'll take the 09. Only lose $1,000 on the trade in for the Passat TDI, I'll take the 89 next year on vacation, or if I finagle another month off with swaps.

Still up for beers on the trip...

Maybe on the diesel one but most I have seen still haven't changed. Still cardboard epoxied to the filter element and 1/2 of the filter element that good ones have.
