For those of you who are following this thread for inspiration or knowledge let me put something out there. If you are lucky enough for Otis (Good&Tight) to share his knowledge with you take it as gospel truth and don't let anyone tell you different not even a hot shot machinist.

After running the car for almost a week with the turbo installed I have noticed a "hiccup" at 12 psi at WOT. At first I thought it was my timing being slightly off but then I also had a couple of overheating situations where I lost a lot of coolant out of the overflow tank. I had to admit to myself that I had a head gasket issue. So I tore into it this evening to confirm. ONCE AGAIN, Otis's advise is the gospel truth!!!!!!!!

You can see where the exhaust pushed through from two cylinders under the head gasket. There was only one that leaked above the head gasket.







And the underside of the head. ONCE AGAIN OTIS IS THE TURBO M30 GOD!!!







But it is not all bad. I had a couple of visitors today.

First a 1972 3.0 CS came in because of a driveline vibration. A loose driveshaft slip joint nut and Guibo bolt tightened and it is back on the road.





Then a local was out for a test drive in his newly finished project and he stopped by.

Is th at the CS that was at the BBQ 2 years ago and was the blow out a result of the bolts, head gasket or both ?

[RagtopE30]

Yes to the CS. And the blow out was the result of improper prep and install of the hg. Like I said, if Otis recommends a certain procedure for installation it is best to follow his advice.

[LJ851]

When you posted about the overheating the first thing i thought was head gasket but didn't want to say it and jinx you.

What are you going to do differently this time ?

[RagtopE30]

Copper spray and multiple rounds of torquing at each interval with "rest" time in between each pass. And I am going to paint my intake manifold

I read that too...painted intake manifold is essential to a proper HG install

[RagtopE30]

Absolutely! I mean come on, no wonder it gave out when it has low self esteem! Painting the intake will boost it's esteem and therefore will prevent further overheating issues, or steam events!

[jeffnhiscars]

People forget that engines have feelings too.

[RagtopE30]

Boosted esteem = no steam with boost

People forget that m30's are ugly as shit!

Fuck those m30's...

[RagtopE30]

^ not cool man! I had my phone read that aloud so my car could hear it, and it immediately sprung a leak!

He's in Aus so figured he could get away with posting that. Wait til he read about your amphibious mod and your cars bad attitude
