Cowl seal is garbage and it happened when we had all that rain in pa
And the miss makes me scratch my head too because I know the bent rod would make it shake but how would it make it miss I’m a ****** when it comes to diesels
When we had all that rain my truck was pointed down hill a small grade I got in it made I believe 2 rotations then locked up I thought it was the starter so I smacked it a couple times and messed with the key and it fired up that’s when I heard the knock when I had the valve covers off I double checked all the springs and everything seemed fine I rolled the push rods and they were all straight I’ve changed injectors so far and the noise is still there as far as fuel goes I do have a leak in my tank but it’s been that since I’ve bought it and has never made the noise/problems and how do I go about getting ahold of Mel I’m willing to try anything at this pointBefore you start thinking about bent rods, did the engine actually hydrolock on you? As close to the head as these pistons get, it doesn't take much water in a cylinder to hydrolock. When it does that, the engine won't turn over to start. If you got in after a rain, hit the key, and the engine wouldn't turn over, that it hydrolocked. If that didn't happen, then you most likely don't have any bent rods. Then I'd be looking back into your fuel system. I'm pointing all of this out since I didn't see where you said that your engine actually hydrolocked and you got it running again. I read your first post as somebody suggested that your engine hydrolocked. In that case, don't listen to that person any more. Another thing that I noticed was that you said the shaking almost stops and the tap dies down. If it was a rod, then the engine temperature probably wouldn't affect the sound. I'm pretty certain that a bent valve would be the same. If your engine has a lot of miles on it, then your thoughts about a bad lifter may be valid too. If it's a weak lifter, then the problems starting during/after the rain is probably just a coincidence. When you had the valve covers off, did you happen to check the valve springs? I know that they can and do wear with age and they also break. Your engine can still run with a broken valve spring. That's just another suggestion to look at before assuming that you have a bent rod. If all else fails, I believe that Mel is in Pennsylvania as well. You may give him a call to see what he has to say.
What numbers would I be trying to look for and how do I determine if it’s valve or rod or is that basically down to tearing into it and finding out that waySpending money on fuel parts isn’t going to fix your problem, these pumps and injectors are pretty robust, and don’t fail overnight. I’d bet money on a bent valve or rod, a compression test will answer that for you.
When I suggested this, I was thinking that maybe he could take a look at your truck. I wasn't suggesting that you buy fuel system parts. You can give him a PM here. His user name is Agnem. You could try to get a hold of him at work at 717-806-5561. If you have a bent valve, that cylinder won't have much compression at all.how do I go about getting ahold of Mel I’m willing to try anything at this point
This still doesn't sound like hydrolock to me. I could be wrong, but usually you can't "unhydrolock" an engine by hitting the starter and messing with the key.I got in it made I believe 2 rotations then locked up I thought it was the starter so I smacked it a couple times and messed with the key and it fired up that’s when I heard the knock
