My New R33 GTR - so it begins...

[NismoS-tune]

I know the feeling friend. 4th summer for me with a car in pieces! I lost a newly built engine last time tho.

Who built your engine and set your tension? It's odd there's some skipped teeth GTRs around lately.

What's your plan? Part out and get a faster mustang for less money and warranty?

I did it with some help from a mechanic friend. Gonna see the extent of the damage and try to rebuild! If just valves won't be too bad.

Tension setting of the cambelt is very critical , especially on an engine where the cams spin up to 4000 rpm or beyond . Pull the head , hopefully its a valve slightly kissing a piston or depending on your camshafts another valve , they will bend easily preventing them seating correctly losing all the compression . Pray you do not have cracked piston crown . valves are easy to fix .

Also check the valves guides to make sure they are not cracked , they are brittle and tend to crack around the bottom if the valve gets sideways stress like this .

Thanks for the tips Paul, fingers crossed!

So yah, bent intake valves...

At least the pistons look OK, no damage I can see.

Very nice build so far! Sorry about the valves :/

[PurpleStreak]

Sorry to see the setback. Just curious, did you deviate from the FSM procedure for setting the tensioner in any way?

[ColinR33]

I probably did, can't remember.
