Compression and leak down test help


Recommended Posts

I have a oil leak problem coming out of the O-rings and out the exhaust. I was already told might be the crank seal. Before I get to ripping this thing apart obviously I should check the leak down and the compression and each cylinder. So can I leave the exhaust and pipes hooked up to the exhaust ports when I do the compression test? And what about the leak down tests, do they have to be removed and capped off?

Motor is in 02 as stock bought a man and tranny never taken apart that I know of but strong. The top and I rebuilt 30 over and ported the cylinders about 15 ride hours ago. I have LRD adjustable race pipes so they are two peas so the seal around them or 100% and it was leaking oil from there for the first time ever. Also around the O-rings which never really fit right because of the pipe flange it leaks Oil from the O-rings on to the motor. I even replace the O-rings several times and even put two springs on each spot instead of one. Just recently I put high temperature silicone around the O-rings to stop that blow by with the oil and this is the first time I'm having a problem with the oil coming out of the pipe where it adjusts at. I was told it could be a crank seal but I don't want to think that way right away I'm wondering if oil is just blowing by the piston ring. I'll only know that by checking the compression first and then take the pipes off to do the leak down test. Any more info would be helpful at this point.

The main problem with where I'm getting at is a lot of smoke was coming from the right pipe even after the warm-up excessively to the point which I've never seen it before. So I'm wondering why this problem is occurring and where it's coming from.

Reeds are in good shape brand-new about 10 hours ago. V Force 4 's and I haven't checked the dipstick in the last ride or two but I changed it about 3 or 4 quick rides ago. I am going to do a compression check to make sure it's not the ring on the piston and then do a leak down between the two of those I should be able to have it narrowed down.
