For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Basic 944 motor question

Post  Admin on Sat Jun 20, 2009 9:21 am

I just bought an 84 944 NA from a guy that had put a new head on the motor. The car runs and drives, but it runs like crap! (what would one expect I only paid $150 for it Very Happy ) I think it has a bad lifter or poorly adjusted valve. There is a lot of valve train noise. I looked through the CD manual that I was given buy Greg, But I could not find any thing about adjustments. Does anyone have any info about this? I would like to get this car running better and maybe make it street legal. It could make a nice commuter car and I hate to part it out just yet.

Someone else may be more help, but here's where I would start...

1) [Not being a wise guy] Do you have oil pressure? The hydraulic lifters are non-adjustable.
a) If no, check / clean the pressure reducing valve. This little monster will clean a 2.5L's clock...
b) I kinda doubt this one, though. They only run for a minute or two with no oil pressure before locking completely. Inspect the oil closely anyway...any "shiny", and it's a paperweight...
2) Are the timing / balance shaft belts in good condition, installed properly, and adjusted properly? It takes a dial indicator to get them 100%.
3) If the timing belt is loose or far enough out of adjustment, big things can happen in that small package...(valves may be introduced to pistons, etc.)
4) Spark plug condition...any lean or rich cylinders? Extreme cases of flooding / over-rich can wipe rings and bearings...
5) I remember something you said about water in the oil...How much? Oil milky? It could wipe out a main bearing...and again...paperweight.

I would start with a simple compression test. See if all the valves are seating and sealing ya know.

Then, with a timing light, I would pull the plug on the distributor and see if timing is on or off drastically. If its pretty good there, then check the flywheel and "OT" mark to alignment mark....follow this page...
