Porsche 944 Timing Belt Failure BENT Valves

Porsche 944 Timing Belt Failure & subsequent results. Got a 944 Porsche 2.5lLiter 4 Cylinder. Unfortunately it has an interference head. Some mechanics tried to "fix" it not knowing what "interference" means. They replaced the timing belt and bent the valves even more. They gave up the 2nd time around. Good thing they never finished the job as it would not have worked anyway.

Whats that part that the cap and rotor is attached to? The porshe Im wanting to buy has a hole in that part, how to fix? Thanks!

@airsoftcrazy456 That would be the distributer & shaft. There is a treaded hole on the side of the shaft for a set screw that the rotor onto the shaft.

honestly it will buff right out lmao

[merkur102]

@1sickasscobra98 Sounds like you buff a lot :)

@ 1.22 the head gasket has got turbo printed on it, are they the same gaskets for the naturally aspirated engines or am i missing something? :)

[merkur102]

@pikeant83 very observant......same part. Guessing it's an upgrade for the naturally aspirated engines.

2:53, alittle more wear and tear and you could almost use the last rod as a mustang gt shifter :D

@Lillie1986 Ok fine since you are going to include the 928 engine as its original design, I will include the FJ20et which was developed in the same era and is superior to the porsche 2.5 liter engine in every shape way and form. Featuring dohc head design, dual valve springs, and over square design to allow ease of revving. Production samples saw hp rating as high as 275 hp in the early 1980s, with racing specimens in the 500 to 600 hp range. home modified version ofc exceeding 1000 hp.

@Inabj2 The M44/51 that sits in the older turbos is the same engine as the M44, without the turbo, which in essence is half a V8 from a 928. The engine from the 928 was launched in 1977.

The 944 engine is also dead reliable and easy to tune.

@TutorialTipCom Although you are correct in that there are quite a few non interference engines, if not most of belt driven engines out there are non interference engines, I would also argue that a high performance engine would be inherently end being an interference engine, due to higher compression ratio, and greater valve lift needed for increased power. Although I would not call the NA 2.5 liter porche a performance engine :P.

@Lillie1986 The Sr20det as we previously discussed is NOT much newer, its maybe perhaps 8 years newer, and maybe 4-5 years newer then the 944 turbo engine . The 944 Using a 2.5 I4 that is of different design and origin (the 2.5 based off 928s V8 minus half the cylinders) then the older 2.0 Audi sourced I4 found in the 924.

But if you want a Nissan 4 cyl engine that is OLDER then the 944 engine, then look at the FJ20ET, dead reliable and almost just as good as the lighter sr20det.

@hamronD73 Not a turbo

[Lillie1986]

@Inabj2 You dont need a new head every 25k miles if you change the timingbelt when youre supposed to. There is absolutely no issues on these cars if you service them like Porsche ment you to do.

Also I dont understand why people compare the 944 to cars and engines that are much newer and then say theyre better, ofcourse they are the car is almost 30 years old.

[Lillie1986]

@TutorialTipCom Its a 25 year old fucking car for gods sakes. How can you possibly expect it to be as good as a brand fucking new car?

[TutorialTipCom]

@Lillie1986 Porsche 944 is a piece of shit compared to other Porsche models. For sure it is better than most domestics, but still, no where near the 911, Cayman, or Boxster!

[TutorialTipCom]

@Lillie1986 Plenty of engines, non-interference ones, the valves will not be affected by timing belt failure. They will stop running for sure until you change the timing belt.

Another thing with the interference engine is that there is a great chance of bending the valves if the timing belt jumps few teeth. On other engines, it's okay, but it will run like shit or it won't run at all. Timing failure on those cars driving 50 mph may actually fuck up the pistons, not just the valves.
