I just got a 1992 sc400 is it a inteference or non interference engine
 

I just got a 1992 sc400 is it a inteference or non interference engine? The timing belt has hair line cracks al over it.

Can anyone confirm or has info on the web or from personal experience. Need answers tahnk you

=):)

google it...

non interference until 95. and you don't need to google, the forum has a good search function

The V8 is non interference? huh, I thought timing chain cars were. I Guess you learn something new everyday.

I had timing issues on my 93 and the valves either got stuck or bent. My compression was like 240psi...i know right...

So is my 1992 sc400 v8 interference or non interference engine? Kinda confused here as i get conflicting answers. Any experts knows for sure?

thank you :)

Your engine is not interference being that it is a 92 and they did not go interference until 95 when the compression was raised. The motor does not use a timing chain, it uses a timing belt which either way has no bearing on interference or not.

Klaus answered you correctly about your engine. As long as that is a 92 engine, you are definitely NON-INTERFERENCE.

which means incase my timing belt breaks , cause there are hair line cracks all over it , then there will be no engine damage from a timing belt failure? thank you in advanced =) sc400TT.. anyone?

Correct. Non-interference = no damage :thumbup:

i have a 95 sc400,so that means mine is interference?
i did not know this..i just assumed it wasn't...glad i change my belt....

How is 95 any different than 92? Along with 96 AND 97?

The only differences in those engines is the OBD1 to 2 upgrade, EGR change, and lighter rods to get some extra power...

ALL NON VVTI 1uzfe's are NON INTERFERENCE!! (1997 SC400 and older)

The only INTERFERENCE engines are the VVTI 1uzfe's. (98+)

Im with redpheonix on this, everywhere i researched to figure out what what wrong with my 1uz said 96< was non-interference. Im 90% sure all OBD1 are non-interference, the OBD2 is the "re-design" of the motor and interference heads. Just take care of your car, do regular maintenience and hopefully you will never have to find out the hard way. Comming from experience The timing belt and the cooling need to be looked after! Other than that its bullet proof...Makes me wanna shoot bullets at my 1uz to see if it really is...lol

I am still looking for proof on the issue of the 96SC400 motor being interference or not. It appears that there is still no concensus on the issue of which were and which were not interference motors. Will someone please provide proof of which years were actually non-interference? Once again, proof please. Not anecdote, not hearsay, but proof. Thank you kindly.
