I heard 3.0 nissan quest engine is modified maxima engine and non-interference.
But when i called the nissan dealer service i was told it is interference as maxima.
WTF?!
Any one has any clues?
I am trying to help out a friend's 1995 quest for a TB job.
TIA.

 

I'm guessing the quest has the VG30 motor, which IS an interfearence motor, you time it wrong your gonna bend valves.

Troy.

 

Whoops, guess I was off on that one, sorry. It is non-interference.

 

I've heard it's non-interference on many occasions.

 

I heard that ford wanted the engine to be a non interferance engine... so nissan changed a few things to make it so..

 

Quests have a NONinterference engine. The reason the Maxima is is because there is less space between the piston and valves which gives you a higher compression ratio which equals more power.

 

Yeah wawa, I guess that Nissan dealer you called was full of crap.

 

why dont you just turn the engine manually after you are done? that will tell you for sure if it is not timed right. if after two crankshaft turns it is still turning go ahead and start it with no worries.

 

I agree. I have seen too many dealer service guys ignorant.
Thanks all.
