VulvaS40T4 Posted April 25, 2015 Author Report Share Posted April 25, 2015 (edited) So long story short. Stock headgasket was on limit and blew on 4.gear pull with 2.8bar boost and 7000rpm. Coolant from exhaust and broke 2cyl sparkplug same time.Tested injectors and everything perfect 1760cc before service and 1780cc after service on 2bar base fuel pressure.So new custom copper headgasket next and new piston rings and also new kts 4022 compressor which has 10mm bigger exducer side which makes it more better for high pressure ratios. More pictures and info after custom headgasket is ready. So 700nm on long term was limit for volvos stock headgasket. Same limit is 800nm on 5cyl and 900nm on 6cyl whiteblocks.

Tightmopedman9 Posted April 26, 2015 Report Share Posted April 26, 2015 I'm assuming the stock gasket was not MLS? Quote Link to comment Share on other sites More sharing options...
VulvaS40T4 Posted April 26, 2015 Author Report Share Posted April 26, 2015 (edited) There is no MLS headgasket available on 4cyl whiteblocks or 6cyl whiteblocks. New headgasket will be better than MLS. Edited April 26, 2015 by VulvaS40T4 Quote Link to comment Share on other sites More sharing options...

Simply Volvo Posted April 29, 2015 Report Share Posted April 29, 2015 Shame to hear about the head gasket going.New gasket is looking great though! Quote Link to comment Share on other sites More sharing options...
Tightmopedman9 Posted April 29, 2015 Report Share Posted April 29, 2015 I'm surprised. I thought you'd be o-ringing. Is that solid or layered? Quote Link to comment Share on other sites More sharing options...
VulvaS40T4 Posted April 30, 2015 Author Report Share Posted April 30, 2015 (edited) This is solid with layer on top and because every oil and water and cylinder hole is 0.1mm higher it will work same way as o-rings on block and give higher force. Thats why this is special and not normal copper gasket. Edited April 30, 2015 by VulvaS40T4 Quote Link to comment Share on other sites More sharing options...
fyrken Posted April 30, 2015 Report Share Posted April 30, 2015 There is no MLS headgasket available on 4cyl whiteblocks or 6cyl whiteblocks. New headgasket will be better than MLS. We use the 5-cylinder head gasket on the T4-engine. Modified obviously.For the 6-cylinder there is a MLS gasket available at Volvo and this works really well. Part no can be found on Salt Slush Racings blog.Erik Quote Link to comment Share on other sites More sharing options...
VulvaS40T4 Posted April 30, 2015 Author Report Share Posted April 30, 2015 Volvo has clearly forgotten this little engine when upgrading those headgaskets on 5cyl and 6cyl white block engines. Still 700hp from 1.878cc engine with stock oldstyle headgasket is lots of power and i have driven about 5000km with this setup before this failure. 1 Quote Link to comment Share on other sites More sharing options...
