What Head gasket do I have on my YB COSWORTH??...Please help!!
Hi all, Rebuilding my cossie for my MK1 ESCORT, my first time doing this, I've measured the thickness of it and it's at 1.5mm after compression, it's a 3 layer gasket, metal, no part number or anything on it, no make on it, the only person I can see on Google is Obbliger performance that has a 1.8mm before compression, hence I thought it might be from his company etc, does anyone else do 1.8mm WRC "4 LAYER" gaskets for yb's...I'm hoping to get 4 layer Victor Reinz maybe, would it matter if I got a 1.3mm gasket?....also which is better, 3 or 4 LAYER, plz help.....Thank
