All overhead cam engines are valve wackers if the timings out .

"The SOHC and trooper DOHC ones are closer tolerance so it 'may' be possible to hit a valve but generally not."

I'd say that it is non interference. I was driving at 60 on the M66 when my timing belt went with a bang.
Got recovered home, put on a new belt and away she went.
Mine is the SOHC like most. The DOHC is quite rare from what I have seen and has the coil pack at the back, I wouldn't know if that is NI or not.

All Isuzu V6 SOHC 6VD1 & DOHC 6VE1 engines are definitely NON interference.

This is in complete harmony with JLemond (guru) posts on http://forum.planetisuzoo.com
Ignore belt manufacturer sites like Gates - their info for these engines is wrong. My assumption is that they propagated the info from the Isuzu 4 cylinder motors.
This is one of those cases in which the web makes life difficult isn't it

Interference - valves and pistons collide when cam belt breaks non - they don't

I'll assume it's a genuine question Joe . Simply put, there is always clearance between the fully open valves and TDC pistons when they are out-of-sync due to a broken or misaligned timing belt.

Yes.

Thank you Boritz,
definately a genuine question - not delved that far into the engine yet.....yet!! So, if worst came to it, and belt was out - it wouldn't do too much damage? is that right? and would just be a case of realigning the marks with the belt? |
