Knocking After warming Up

[Mrcln1]

Went out and looked at the egr not and it's cross threaded. It's going on at a pretty good angle. I guess the dealer didn't bother to fix it or couldn't. I don't have the tools I need with me right now to get at it. I'd like to take the whole tube off to make sure I get it on right and look at the damage but it looks like it's damn near impossible to get to the bolts behind the motor. I started it and it ran perfectly for 10 minutes. I revved it slowly and the knock comes in around 2000 rpms. I still can't imagine that the egr not could cause this noise. It definitely sounds like knock from the front bottom of the motor. I hope the nut fixes it. I'll keep ya posted.

Thanks Guys,

when i found my egr nut was the problem i was in the engine compartment with it running and i was manually reving it with the throttle mechanism right on top of the motor,it was very difficult to diagnose cause i too swore it was the engin nocking and it would only do it when reving and not at idle so when i reached under the egr i felt the suction and wrapped my hand around the tube to block it and there it was,that was the prob,and my nut was just hanging on the tube not even threaded in at all thanks to a someone not putting it back in after replacing my intake gaskets.

I'm not sure now what the deal is cause the hose is at an angle coming off so it may just be my eyes playing tricks on me. The nut is soo tight that I can't get it loose with my shortie wrench. I don't feel any kind of leak and after it warms up and the the knocking makes a klackityklack noise when you rev the engine. I can't ven imagine how it's possible to get to the back egr connection. My buddies 2002 rodeo doesn't have all the crap on the left side of the engine bay in the way and we barely got to it. It's going on a rollback to the dealer tomorrow probably.

Thanks Guys,

Most shops wanted $300.00 plus to take the VX to the nearest Isuzu dealer. The towman will do it for $195.00. It's over an hours drive for me so thats not bad. He'll be here in a little while to pick it up. Man I hope it's repairable cause I just have a feeling that they will give me a hard time over the warranty. My mechanic worked at a Ford dealer for 4 or 5 years but I don't know if that will be enough to persuade them that he's good enough to sustain the engine warranty. I think he needs to be ASE certified but I'm not sure if he is, was, or is anymore. I'm not sure how strict Engines Direct is. It ran for 4 or 5 thousand miles just fine so it should have been installed just fine I guess. I don't know. They'll look at it Friday morning and let me know the deal.

Thanks for the help guys. I'll keep you updated.

I suspect that the 6ve1's crank is not strong enough to survive after substantial regrinding. It looks like my broken engine's crank had been ground and replaced with new bearings and pistons. If the crank was already at tolerance, grinding off metal at the journals will only weaken it. Nearly all engine remanufacturing shops regrind their cranks and most of the engines they start with have spun a bearing or something similar, forcing more than minimal grinding.

I really, really hope that yours does not suffer the same fate as mine. At least if it is a broken crank, it should be nearly impossible for them to blame it on anyone but themselves. Even the worst installer would have a hard time causing that catastrophic of a failure. At least I keep telling myself that

I hope thats it too. They got it Thursday and were supposed to look at it Friday morning but when I called the service manager said he had a certain mechanic he wanted to look at it because they only have one chance at this. I was glad to hear that. Makes me think they know exactly what they are dealing with. Still haven't heard anything as of today but I've learned not to rush body shops or mechanics. lol I'm taking care of the no 4x4 thing tomorrow though. I'm trading my 05 GTO for an 05 Rubicon, all black. I think the Vehicross is gonna turn into a 2wd S10 with the sport suspension when it's repaired. I really liked it till it broke, now I worry about it and my work doesn't accept excuses. I really appreciate the help you guys have given me during my one year as a Vehicross owner and wish it would have lasted longer. I'll keep you guys updated as I find out the deal.

Thanks alot guys,

Talked to dealer yesterday and they said it was rod or rod bearing knock. Called Engines Direct and they called Proformance Engines. Warranty guy called me said that they pay $50 an hour labor up to $600. I wanna make sure it's as right as possible this time so I'm gonna get the dealer to do the install of the new engine. He said as long as they can confirm it failed from the reman process they'll pay. Is there anything that I or the installer could have done to cause this? It ran perfect for 4000k. I'm gonna end up with a hell of a bill from the dealer anyway cause they charge $80 an hour labor and the installer only pays $50 an hour. Just wanna make sure that theres nothing that was done on my end to cause this. Also after this I really recommend getting an engine from a dealer. It seems worth the extra cash to have everything covered completely. Especially after what I've been through with this reman. Of course the guy at Proformance said I was lucky because most warranty companies don't pay as much as Engines Direct will.

Thanks For The Help guys,
