valve timing problems

i just recently put an ed xr6 engine in my ea and i pulled the front of the motor down and replaced a timing chain guide and when re assembled it iam not sure if i got the timing right , does anyone know exactly what the consequenses would be if you had the timing one tooth advanced or retared.

The car feels like it has nothing untill about 3000 rpm and then it picks up and goes.

red ea s-pack 5 speed, engine, 4 wheels + spare, steering wheel, brakes, suspension, exhaust, 20w x 4 stock standerd stereo system, diff (rear wheel one), clutch, seats (including 2 retractable front seats) all with seat belts. Performance Mods : air filter removed, fuel filter removed, some guards taken off for weight reduction.

Re: valve timing problems

Mate if it helps...line up the timing marks on your crankshaft to tdc.At the pointer.Then look at your camshaft sprocket mark.Aparently it should be above the head 3mm on the passengers side.Dont take my word for it ..but I am pretty sure its how it works.I am not a mechanic.

It sounds as though your timing marks may be higher than this and your cam retarded.If so take the sprocket off and realign it properly

But be careful and double check with someone else too..

Re: valve timing problems

From what you say it sounds like its one tooth retarded maybe two!

Take the rocker cover off and check the dot on the cam gear at tdc no1 against the rocker cover head surface level it should be 3mm higher or there abouts.
