Loss of power, leaking oil from front of engine, heavy vibration when idling - please help.?

Sounds like your have a head gasket problem. Check your coolant level. Also look at the block to see where the oil is leaking.

Either way it needs to be diagnosed before more serious engine damge occurs.

you do not say the form o' cylinders -or IF that's a carburetor mill. As you would understand, a element like a Harley has a ,growth-growth' abnormal firing order an' so calls for extremely rather till now beginning on the intake cam lobe. think of a-bout this: basically approximately all 4 cyl [carburetored] engines are the comparable .. they actually require 2thou tighter clearances on the [2nd-firing] OF the paired cyls. (necessary on a element like an M.G.B).

That could be any number of things. You could have snapped a rod or a crank and cracked the block. You could have blown a piston ring which would cause it to lose alot of power because no all the pistons would be firing. I suggest just take it to a shop and get an estimate on it.

2 ever tuned up

3 ck engine lite on
