Hey guys just a comp test done on my sei and all came back exactly the same and equal does this mean the hg is good of could it still have a fault with say a water jacket etc ta
Will mean HG is fine (unless all spectacularly low!). Since pressure in cylinder is much higher than in cooling system, rules out an issue at the interface between cylinder head and water jacket.
Ah OK great and just a slight lumpy idle and holding back slightly when cold once warm it's like a rocket lol think it just needs a good service the cam cover breather was blocked with thick tar like oil etc
If it's not loosing coolant/overheating chances are that all the coolant system is fine. Good service never hurts. If in doubt, Allitalia, Paxton Garage. Llewelyn Rd. Vron, Tanyfron. Wrexham. Try and talk to Howard. Good man.
