Looking good shags

yeah the arp bolts are good

do you have one of the ring compressors with the flat straps you ratchet up to tighten ? I've found with them you need to get the bottom of it just below the oil ring, then tighten as much as you can, then get it in the bore and tape around the top of the whole compressor to make sure all of it is right up to the bore before tapping it in.

Thats what I have been doing. The little ratchet thing on it is kinds between 2 teeth, so it means I have to keep it tight by hand while I tap it in.


Just a question, how critical is the locations of the ring gaps in relation to the piston? I found the rings move around in the process of tightening the compressor. I can see after the gaps have moved by the oil streak left in the bore.

on the 2nd piston its moved by about 15º. Is that ok?

I noticed the factory engines have the gaps pretty much random, more than often lined up lol

best to try and get the ring gaps opposite each other at the gudgeon pin( least piston rock area). oil control 30deg apart
so I go for top at front second at rear oil control at front .
but i wouldn't be doing them again for 15 deg.But then that depends on how ocd you are

yeah im similar, just trying to keep the gaps away from the wear sides..... also depends on the motor too, but also try to keep the gap away from hot exhaust ports etc.

yeah that ocd, its playing on me haha.

Im just following the workshop manual for the gap location. they just oppose each other. The manual says to set them at 90º from the pin with the oil rings and lower comp ring away from the trust side, top ring is to the trust side but its a really thin ring compared to the lower one.

[Holden202T]

I think its one of those things, every man and his dog have there own opinions on whats best, so just do what works best for your OCD

[vlad01]

I couldn't help it, had to pull that one out again and rotate them a bit.

Happy now!

Just set it at TDC to see what the deck height was like, more for curiosity than anything. Measured 0.008" Thats pretty small lol.

that's not that different to the .01 I have for a stock VR v6 though ?
