I am in the process of replacing the timing belt on a 1993 Eagle Vision TSI with 3.5L engine, which has the same engine as the Intrepid 3.5L. I changed the belt on this vehicle in 2001, and I had no problems. This time, after aligning the cams between their respective "two timing marks" at crankshaft TDC, I removed the belt with no problem. However, when I began to install the new belt I inadvertently moved the left side cam (viewed from the driver's side), and it jumped CCW about 90 degrees. I was certainly stunned at this development since I am aware that this is an interference engine. Well, I proceeded to turn the cam CW back between the two timing marks, and successfully installed the belt. What is the likelihood that the left cam is not at TDC? Is there a simple way to check for TDC. I certainly will not start the engine until I am sure both cams are at TDC. Thanks for any help or advice.

I believe there have been several discussions as to weather or not the first gen 3.5L is actually an interference engine or not. If I recall correctly there are many many who swear that it is not an interference engine and that despite having their timing belts break while driving nothing at all was damaged.

i had a hell of a time with my ford's non interference engine. Im not sure about chryslers but the ford engine had no marks. I made my own marks with a permanent marker and grinded it a bit with the dremel to have them there for later service.

If you have marks to look at, that would be ur first step and then those mobile mechanic services may also be a good idea to look into just to have it looked at. IF i knew what i was doing in a trep i would certainly come over and give you a hand, im sure there are other such members which may be able to lend a helping hand.

Good luck

No Problem

FWIW, I was able to answer my own question. After returning the left cam back to the TDC position, I installed the belt, and manually turned over the engine four revolutions, and heard nothing. I then discussed my problem with a local Chyrsler mechanic, and he said it was likely no problem. This morning, I started the car, the timing was perfect and no engine noise. Bottom line, no problem.
