ok.. so I just built my own leakdown tool..

I was on c-speedracing, and read their article.. but just would like to clarify a few things.

If I can hear/feel air coming from the:

Oil Cap - ?
Oil Dipstick - ?
Radiator Cap - Headgasket
Bottom End - ?
Intake(throttle plate) - Intake Valves
Exhaust - Exhaust Valves and anything else????

What is wrong with the ones with the question mark.

Thanks everyone.

 

no one has done a leakdown test?

 

should the engine be warm or cold when doing this?

 

you're leaking through the rings if you're getting air from the oil cap/dipstick tube.

Engine should be warm. This poses a dilemma since you're not supposed to remove plugs on a warm engine but how you supposed to get it warm without plugs in it??? Just be careful when taking the plugs out.

 

ya i know.. ill be carefull with that.

a shop said that if i brought it in, that id need to leave it there so it could cool down???

 

does each cylinder need to be set to TDC???

TDC compression

what does that mean???

If I set Cylinder 1 to TDC, is that all I have to do? or do I have to set EACH cylinder to TDC???

 

is it necessary to post the same damn thing twice????

 

BTW, you will hear atleast some air coming out of the engine...even if everything is in good condition.

 

TDC of the compression stroke (all valves closed) vs exhaust stroke (all valves open... slightly)
