Leakdown test results...what would you do?
On my '99 Honda CR-V...it has about 205K on it. I just took it to one shop, I was hoping that they could fix it before we went out of town. But, they did a compression test and it had 135 or higher, in 3 cylinders and #4 had 35#.
So, I take it to another shop that takes forever to get in to and we leave it while we are out of town. They adjust the valves, #4 has no lash at all on the exhaust. You could not move the rocker arm. He starts it and it runs fine. I drive off and when it warms up and goes off of fast idle it starts throwing the same code (P1399). We only notice a problem at idle.
I was hoping that a valve job would fix it, but now I am not so sure.
Today, I do a leakdown test. The only good thing about it I can say is that there was no leakage in the radiator or exhaust.
#1, air leakage heard in the valve cover (caused by leaking rings?)
#2 you could feel a draft coming out of #1 and #4
#3 leakage heard in the intake manifold
#4 draft in #3 and noise in #1
This is very odd...for instance, #1 is not audible in the other cylinders...But, #2 and #4 both have symptoms in #1. When I say a draft, I mean that when you put air in to #2 and put a rubber hose against the sparkplug hole and your check you can feel air coming out of #1.
So, based on the above....Can I safely assume that a valve job is a waste of time? Correct?
Has anybody had any luck w/JDM engines...do you have a recommendation?
