Hi guys, long time lurker here. I just have some newb questions for you 944 guys.

What are the weak spots for the 944 motors? I have heard rod bearings.
Are you baffling the oil pan, or using Accusumps?

What would you recommend doing (spec legal) to increase longevity?

Thanks,
Chad

Great question...
rod bearings are a must as is a timing belt. from there it kind of depends on your budget.

I value an oil cooler and new radiator over baffles and accusump , but if your in the engine a 88 oil pan with trap door welded in is nice to have.

please keep up the questions and what region are you in ?

944 motor are actually pretty solid.


Rod bearing is the only weak spot. Timming belts nearly always get changed and therefore a pretty much non issues.

For rod bearings do the following

1) Top off (not over full) oil each session
2) Minimize oil leaks/consumption so as to keep the oil from going low on track.
3) use high quality 15w15 or 20w50 oil (racing oils like redline, amsoil etc)
4) Fresh rod bearings
5) trap door baffle
6) Oil cooler - 951 style or similar
7) Fresh main bearings
8) change rod bearings every 2 years.

Do the above and rod bearings tend to last just fine.

I'm located in Clovis, Ca (Fresno) Smack dab in the middle of CA.

I have only messed with 911 motors, never a 944. What can you do with the engine in the car? Or do you just take it out like us 911 guys?

in the car you can change a head or change rod bearings. If you wnat to change main bearings you need to pull the motor.

The crank is too heavy to remove in the car. You probably could do it, but at that point is just not worth it.

What I do is change rod bearings, timing belt, get a valve job, inspect rollers. AND RACE IT !

SO far So good. but after 2 seasons or so it will need to be pulled and new main bearings added to the above list.
