Maybe. But the new seal didn’t include this outer cap.

Thanks Eric. I worked on it a little more today with a new leak down tester. I had about 90% loss. Most of it through the intake. I took off the rocker arms and ran the leak down test again. the reading came out good, only about 15% loss and I couldn’t hear any air rushing through the engine like I could before. To me that says there is a bad lifter but I cold be wrong. Any advice would be greatly appreciated.

Thank you for all the advise so far. Now that I have somewhat fixed the compression problem I set out to solve the power balance issue. I first tested the injector with a meter and stethoscope. Everything checked out, so aside from making sure the fuel rail is getting fuel to the injector I ruled out a fuel problem.

The next thing I checked is the coil pack. I got the readings
Bank 1: 1.9 ohms
Bank 2: 2.8 ohms
Bank 3: 2.8 ohms
I’m really not good with electrical issues so I don’t know if that means I have a bad bank. I’m hoping someone here can help me with this. Thanks again.

I ran the power balance test and it showed cylinder 1 was the problem. I ran the leak down test and it showed I was losing 100% compression. the only place it was leaking was in the crank case so I pulled the crank case cover and noticed that the plunger for the exhaust valve wasn’t seated. I fixed that and ran a compression test it read 100psi (up from 0). No codes right now but it still sounds like it is misfiring. Another power balance test showed there is still a problem with cylinder 1. I am going to run another compression test and leak down to see if anything has changed.

Anyone think it might be a stuck valve?

Thanks Eric and John. I did the compression test and it came out: #1:55 #2:135 #3:130. I ran the test again in cylinder 1 and it came up 0 on both the dry and wet test. So it looks like there is a problem with the compression on cylinder 1.

Thanks. I don’t really have any signs of low compression. that’s why I’m mot leaning in that direction. But like you said it could,t hurt to check. I have a compression gauge, I’ll give it a try a little later and let you guys know how it goes.

I forgot to mention that the first time this happened I also had the code p1594 (charging system voltage too high)

Driving under the limit is the bast way to avoid a ticket. With that said if you are going to speed skip the radar detector and find yourself a good traffic lawyer. Those detectors only work part of the time and you may make you feel confident to speed more but a good lawyer will keep the ticket off your record most of the time.

Thanks Eric. you solved the problem when other mechanics couldn’t. It was a voltage leak. As soon as I heard you say ” fish biting” I knew that what I had. A friend of mine who is an electrician cleaned up my injector wires and we replace the coil rail now it runs great.
