Fuuuuuuuuuuuuuuuuuck dude. that blows.

You got lucky. That could have caused some serious damage to the block or the turbo.

Yeah, reseated the 4 valves. With a torch there's no light bleed.
Engines back in. Snapped a cam shaft bolt. Got that out.

Setting timing now.

What's the compression bets?

adryargument 07-24-2016 06:30 AM

Compression is now 47.
Back left head bolt is threaded. No wonder it came out real easy and there was oil on top of the gearbox. Previous owner was a bit shifty.

However cylinder 4 was showing 185 then cold with a bit of oil.

There goes about 18 hours. Learnt alot.. Overall quite enjoyable.

Question is do I attempt it again next weekend?

I would personally not run that head or piston. Get a long block or rebuild. Time is too valuable to screw around with janky bits.

Yeah will grab a new vvt motor this week. Have a choice of two. Both are 130k km.... 80k miles?
One is definitely a 2001. Other i'm not so sure. Should get comp numbers back today for both.

At least it will be nice to do a reroute and turbo install on a stand.

do you have something to control the VVT?

adryargument 07-25-2016 09:31 AM

Yeah MS3.
VVT @ 128k km is hanging in the garage. Bonus is the flat top.
Extra parts are alternator / AC / Injectors i can flog to make up some of the difference.

Pulled from a porsche wrecker who claimed 193/194 compression across all 4.
Only issue was the starter was sold before i paid deposit.

Ill test compression before i do anything.
Otherwise there's a slight oil leak from vvt tube / oil pressure sensor area above where the starter was removed.
