coolant pressurising after new gasket etc??? - Jimbo - 19-03-2014
So as most know done my ph3 xud swap,
Built the engine up with new Victor reinz head gasket and head.bolts
All torqued to spec properly.
Now ive got heat in car, and it never seems to run hot like most of my other DTs have.
Just seem to get quite a hard top hose after a longish run
I didnt have the head skimmed as donor car was fine, I cleaned up both surfaces well.
Im gonna try a new stat tomoro but im not hopeful tbh. Just dont want it to.be headgasket failure after 500 miles.
Anyone had a problem before??
Car is running a gt1752 turbo 22 psi ish, on a govd bosch
Cheers, any ideas appreciated

Headlift maybe...?
RE: coolant pressurising after new gasket etc??? - Jimbo - 19-03-2014
I did wonder that, but really?? Its hardly a massive turbo cant be.flowing that much surely
It goes well mind.
Frosty had a similar problem too just winding me up
RE: coolant pressurising after new gasket etc??? - Piggy - 19-03-2014
I did all you did...inc not skimming.
Worst mistake ever. Had to take it off, strip and skim, back together and no issues at all for 7k miles now

Rookie mistake right there always have The head skimmed
RE: coolant pressurising after new gasket etc??? - Chris_90 - 19-03-2014
As said always have the head skimmed and pressure tested to make sure it's all ok, but on another note you built the engine then just wound boost straight to 22psi? Surely that's gonna do it no good, surely it would be best to bed it in first I might be talking rubbish but that's how understood what's best to do.

Even if the gasket hadnt previously gone??
Have seen it done on a few different engines without a problem.
Frosty had the same issue and his was skimmed though

I dont drive like a cnut though mate, I dont abuse it at all
RE: coolant pressurising after new gasket etc??? - padge - 19-03-2014
Mines the same, didnt skim and a week later it popped altogether
RE: coolant pressurising after new gasket etc??? - Jimbo - 19-03-2014
The one you just built padge??
f*cking things wind me up sometimes
RE: coolant pressurising after new gasket etc??? - padge - 19-03-2014
Yes mate its sat on the drive needing another gasket and a skim
RE: coolant pressurising after new gasket etc??? - Jimbo - 20-03-2014
Ah thats crap, never mind ill wack thermostat in tomoro see what happen.
Looks like ill be taking the head back off sooner than I thought. All good fun
RE: coolant pressurising after new gasket etc??? - Chris_90 - 20-03-2014
Got my skimmed and pressure tested head for sale

How much posted chris

As James has said i had the same issue with mine and i fitted all new gaskets etc and had the head skimmed and pressure tested and then changed the thermostat as well and still it seemed to pressurize up fair hard.
Building another engine up at the moment with ARP head studs but i cant see that mine would of lifted the head as my turbo isn't very big. Will whip the head off mine when engine is out
RE: coolant pressurising after new gasket etc??? - anto - 20-03-2014
Its madness not to get the head skimmed when the head is off, regardless of how the car went before. False economy.
RE: coolant pressurising after new gasket etc??? - Frosty - 20-03-2014
You wouldn't say that if you put a head on without it being skimmed and didn't have any issues. I bet many have done it before and had no issues
RE: coolant pressurising after new gasket etc??? - powerandtorque - 20-03-2014
It should be checked for trueness regardless and obviously skimmed if it's anything less than spot on.
I'd guess about 80% of the heads that I've removed from cars that haven't overheated or shown HG issues have heads that aren't true when checked and need a few thou skimmed off them. If you're using an MLS gasket then the head really does have to be spot on as they're far less tolerant than regular gaskets.

Pm'ed you
RE: coolant pressurising after new gasket etc??? - Jimbo - 20-03-2014
Right well ive removed the thermostat and its not pressurising much Anymore so will see how it goes.
Have spoke to darren who has agreed its quite possible that this small frame gt series turbos can lift the head, im not saying that's the cause but it wont be helping at all.
Gonna leave it a.week and decide what to do then depending.how it is
Probably get some arp studs and a 5 notch gasket + headskim/ another head if its still no good
