Oil Priming Possible (87-91) Motors

2Quick4u928 · 11-17-2009, 05:50 AM

Am used to U.S. muscle cars when building motors...On my 88' S4, is there any oil priming that can be done on a motor that has been sitting for a few years prior to ectual engine turn-over?

Thank you in advance!!

Not unless you remove the timing belt.

You could remove the spark plugs and turn it over to prime if you feel that's important.

Pull the plugs, squirt in a bit of oil or fancy stuff like Marvel Mystery oil, let it sit a few minutes and then turn the motor over a few times by hand, then crank til you see oil pressure, then put the plugs back in and start it. I had lifter noise on one of mine that lasted about half and hour, but got less and less.

Appreciate the response guys, will complete. The Marvel M. Oil may be a bit tough but will attempt to network to see what I can come up with. Will keep you all posted, thanks again!!

You mentioned that you have not started it for a few years...

What conditions was it stored in??
Temperature range?
Have you done anything regarding your gas in the gas tank? Any seperation of water from gas...

I would be interested in hearing what you do or dont to about the gas based upon your conditions.

Hey Jon,
Actually had swapped motors due to what I believe was a flex plate/thrust bearing sesure which apparently locked up the motor. Took a bit of time to get the ball rolling to begin the swap out due to family issues and the lot.
everything has been completed now, is only the installation of the cool air duct for the alternator remains. Have opened all the major fuel lines around the motor and blew the lines out with compressed air as well as towards the fuel pump in the tank. This weekend will jack up the opposite end and drain the fuel, add some high grade fuel then flush again and physically verify the tank and clean manually if needed. Lastly will add the high-grade again as with fuel additive and some STP gas treatment. After this will do as the guys meantioned above then pray the ole girl fires up hassle free!

Great, that should do it.

Let it run...

Thanks for the response.....car has been sitting for 3 to 4 years now. Emptied the gas (7 gallons plus or minus), a few days ago...Gas normal smell, looked pure and remained color (Blue) for E.U. high octane. Ran gas treatment through the system and drained. Wife called, left clamp onto pump inlet line but the fuel continued a steady drip and the hot trouble light was not too far away. While talking, was thinking of a bright flash & heat, but was fortunate hehe.
Will add some new fuel next week and drain, then physically check inside the tank (If I can get the locking collar for the sensor removed). Add more high octain with fuel additive and see what happens. Felt confident enough with the old fuel, will dump in with my new fuel in the BMW with some gas treatment, believe ok....will soon see hehe.

I'm thinking about making a wrench/socket to fit the sensor ring. There may also be an actual Porsche part as well, but I have heard of using a T fitting for PVC pipe and cutting notches etc to fit the ring.

Just through I'd give my 2 cents (6 months late)

I believe it is very important to prime the oil pump before you try and turn it over.
I did the mains with engine in the car and just installed the T belt last night but forgot to spin the oil pump and I am going to back step, take the belt off the gear, remove oil pump gear put my air drill on the shaft and spin it up.
When the drill loads up then I will know the bearings have oil before i start dragging metal to metal crank over the bearings.
