4 symptoms. what can be wrong 606 engine?
 
I recently had the head off of my 606 engine. After reassembly, here are the issues:
1. Difficult to start
2. Once started, engine runs very poorly. will struggle to stay alive when cold, but when begins to warm up, if I don't keep foot slightly on pedal it will just die.
3. When idling, it smokes like crazy.
4. The second I drop it into gear, engine dies. Even if I try to keep a little pressure on accelerator.

Have you checked for air leaking into the fuel supply lines?

Nice to rule out the basics first...

fuel filters

mikemass1221 05-14-2009 08:21 PM

brand new fuel filter installed. hasn't even been driven on yet. And we bled the hell out of the fuel lines when putting everything back together. I'm pretty sure we got all the air out. I don't see any bubbles.

Well timing issues kind of boil to the surface. I would check them all out. Make sure the camshaft is on the right cycle. You would not be the first. Why was the head pulled?

My car ran like that when I got the fuel lines crossed. Make sure they're all in the right order. The two that go to the lift pump fit VERY well backward... :(

First off, thank you all for responding. I really need this forum for mechanical help and it has proved successful in the past with all your help.
I very well suspect the timing as well but if it somehow slipped, I wouldn't know where to begin. That being said, we were very careful to keeps things aligned. The reason for the head coming off is a very long story. Simply 2 GP's broke off and all extraction methods failed. I've been out of commission for over 3 months now.

KarTek, Good suggestion on the fuels lines crossed. We'll check that tomorrow. If I do have a timing issue, where do I start?

Here's a picture of the fuel system:

that exploded diagram of the fuel lines is really helpful. Thanks Evan. I'll report back tomorrow.

mikemass1221 05-15-2009 03:00 PM

Fuel Lines all in proper place. No air bubbles running through fuel lines. No leaks. I'm thinking the timing, but everything looks lined up perfectly. Any other thoughts?

You are absolutely certain the lower ends of #83 & #74 aren't reversed where they enter the lift pump?

mikemass1221 05-15-2009 08:18 PM

Yup, Certain. By the way, terry. You were going to send me a pdf file referencing the timing marks about a month ago. Never got it. I think I've seen the same information else where. Either way, I'm 99% sure we got the timing set correctly, so still trying to figure this out. I had absolutely no issues with the way the engine ran prior to head coming off.

TMAllison 05-15-2009 09:40 PM

I believe you didn't email me your email address using the email link here? Do so, and I'll send you what I have.

I have just gone thru the same deal, sans the GP breaking, condolences. My DV's were leaking and when replacing the seals, I did not like the looks of the fuel lines. Hard & brittle, so I replaced all.
This cured the hard starting, stalling at idle, etc.
If those fuel hoses are original, I would spring for new. After changing, I did a diesel purge and I am back to nearly new acceleration, with improved mileage.:)

Good Luck

I'm assuming the smoke is white and theres LOTS of it? If so - that's a classic sign of retarded timing...or you have tractor pulling fuel system parts installed. :)

This happened to me with my old '98.4 Dodge/Cummins with the P7100. I had it all apart to replace the gearcase gasket (requires pulling IP, camshaft, etc.) and while I was at it - I got the timing wrong...very, very wrong. It wouldn't start/idle worth a darn and the smoke was insane. Properly set timing and no other changes - and it was fine.

I'd appreciate it if you could send me any PDF files as well. I'm pretty sure my email address is listed in my profile. Including it here would be an open invite for SPAM. I'm trying to acquire all the info I can get my grubby hands on for the OM606.962...

By the way - what is #155 on that diagram?

Cheers,

Matt
