The good news and the bad news

if it is a head gasket issue then how could that be human error?? not being funny im genuinely curious why people are quick to point fingers when it could be down to a number of things!!

The best thing to do is find out what's happened first it can be quite a few things and only time will tell

what number of things?

[Biff]

All this chat of uprated head gaskets and Russ's Peril runs a standard genuine Volvo one and the liner went before the gasket and that runs in excess of 27 psi

The gasket is the weak point you want to fail first. I've seen many people use steel head gaskets in my vauxhall days running 2 bar & it's blown the block to pieces. Engines aren't designed to have the failsafe removed.

Boost with incorrect map & the adjusted afr with your maf & turbo pipe.

that may do it lol

Just finished my head gasket last week 1k ago, I had a very small leak into the water jacket on number 5, was getting steam out of the exhaust and air bubbling into the heater matrix when blipping the throttle as this is feed from the end of the liner area

good luck with it............

I was pointing out the quality of Volvo's own gasket not the need for an uprated one

Like I said before I'm running a standard gasket and over 26psi regular including 40 odd runs on the rollers I'm guessing something wasn't Torqued down right or wrong bolts used and In using standard bolts

yeah what he said lol

well, tonight i undone the 12 head bolts and what i did notice is that they wasn't all the same tightness at all some were alot tighter than others, everything is off and loose now, all i have to do tomorrow is pry the manifold back off the studs and its ready for lifting off

In a mad way that might be good news mate, means it lifted under the pressure and not the heat and warped, still need to get a skim done to be safe

[graemewelch]

You might as well pull the head off to see wear its blown if it has blown.

always get a skim done mate after all that work lol

of course i'm taking the head off mate, or i won't be able to fit a new gasket lol

[mitchyboy01]

why not just fit the Focus RS head gasket or look for a uprated one for that model, should be direct fit

Volvo head gaskets are more than up to the job even on highly tuned cars. The problem here isn't a bad gasket or too much boost, it's changing the MAF. You can't just fit a 3inch MAF without a custom map too suit. The MAF will under read airflow drastically due the increased surface area. It will run lean and without a custom map it's no better than saturating a stock MAF.

That does sound odd, are the torque to then angle tighten to finish.

I meant take it off tonight numpty.

my thinking was that my car was running very rich anyway, so i was trying to lean it out using a 3" maf, it was the extra boost that i got after fitting it that popped the gasket
