Bent Valves

[peter 20]

Does anyone have an idea of how to check if my engine has bent valves without taking the head off and the engine isnt in the car....

A very crude way to tell if they're bent enough to give you low/no compression is to turn the engine over with a spanner and "feel" each compression stroke - it'll be quite obvious if one (or more) cylinders is obviously amiss. Otherwise, you could just bolt a gearbox and starter onto it along with a bit of oil in the sump and compression test it that way

Sounds sensible thanks! ill have to find a spare gearbox then!

Plus depends on how badly they are bent, You can whip the cam cover off and see what lifters don;t return on the compression stroke
