Hello.
First, I am Egoitz and I live in Bilbao, Basque Country.
I have a mk2 escort with a 2.0 Zetec engine. Fitted the engine is running 803 with twin 45 jenvys injectors, cams Dunellen, STEEL with rods, JE forged pistons, arp bolts, knife edged and balanced crank, arp flywheel Lightenerin flywheel bolts. Its running on dta S40pro ignition.
Now I have a problem. The first and second cylinder not working. The third and fours works ok. The 4 spark plugs work well. I've removed the admission and found to have low revs expelled air those two cylinders instead of absorbing the air as it should occur. I think it can be a problem in the intake valve or a cracked head gasket. Do you think? Has this motor lifter tappet regulation?
Before I start dismantling the opinion of an expert.
