need a little advice...

[RipnRun]

My truck has been running GREAT since I moved the heat sync and pmd to the bumper hole in March. Still something bothering me; even on these warm mornings and hot days, it’s a little difficult to start the 1st time after sitting all night. It doesn’t matter if I let the wait to start light go on and off once or three complete glow-plug cycles, the first time I turn the key it will start to catch then stop. I’ll have to crank it a while before it catches. It’s fine the rest of the day. I used to get code 1409 a lot, but that seemed to pop up only once in a while after moving the pmd and haven’t seen it for a while.

Could I need a new Glow Plug Controller/Relay, or what do you suggest?

Thanks for any help.

My suburban had the same starting probem until I replaced the valve lifters. They leaked over night so the valves would not open properly. You could test this by pulling the ECM fuse and crank the engine until it has oil pressure, then see how it starts.

Thanks. Three questions:

Is this what you're referring to? http://www.ssdieselsupply.com/product_341_6.5_Diesel_Hydraulic_Roller_Lifter.htm l

When I pull the ECM fuse and crank the engine until it has oil pressure then see how it starts, I assume I should do this after it sits all night and that I'm trying to see whether it starts easily?

I don't have the mechanical knowledge replace the lifters myself. Will this problem continue to get worse until they are replaced?

[grancito]

Yes those are the lifters. Leave it sit over night for the test to see if it starts easily. The problem will get worse if that is the cause, and you will get clacking sounds from the valve covers when hot and a waste gate solenoid code which is not a solenoid fault.

I have just realized, your CDR post, you have a lot of blowby, hard starting could be from low compression.

[RipnRun]

What is blowby? Should I replace the CDR or plug it back up like it used to be?

[grancito]

Blow by is combustion gas passing the pistons into the crank case. It is caused by warn rings/cylinders. The oil vapor from the CDR would help compression a bit. Have you had harder starting after you changed the system?

[RipnRun]

I'm not sure. I'll hook it back the original way any try it out. Thanks!

[RipnRun]

Haven't made any changes yet because I've been out of town far a long time and the truck has been just sitting. I went to start it up today, thinking it would be difficult. It surprised me by firing right up as fast as possible. I'll see what happens tommorrow without changing cdr back to original setup.

OK, been having trouble getting it started since last post and batteries seem very weak. Tightened pmd screws. Checked battery connections. Had the alternator tested - alternator is fine but both batteries are bad. I'm still 6 weeks good on the 3-year free replacement. I called the National Tire & Battery shop that sold me the batteries and they said no problem, they'll have replacements tomorrow. Here's my question: they don't carry Exxide Orbital batteries anymore. Instead, they use Eveready Orbital. Are these just as good?

[RipnRun]

NTB switched out the batteries for two Optima red top made by Interstate with 100ca and 800cca. I hope they are good. Got a new warranty with the new batteries; I thought that was pretty decent of NTB since these were free replacements. Truck seems fine now so I hope the lifters aren't needing to be replaced. I also found the CDR Valve Connector Hose and put it back. I'll try that both ways and see if there is a difference in starting.

[grancito]

New batteries helps starting when compression is low, also the oil vapor from the CDR will help.

[RipnRun]

So I guess that is an advantage to leaving the original cdr hose intact. What are the advantages to routing the oily smoke away from the turbo?

No oil on the engine from intake leaks, and no extra carbon build up in the cylinders.

:eek: By passing the CDR works very well for all of those :D
It also allows your air filters to last longer ;)

I had the Red top's in my truck when i got it, they seem to only last about 6 years, the lead acid's last about 4 years in general, but i have the Gel cell's die in 5 years and had lead acid's go up to 9 years . . .


All really depends on quality, power ratings and usage :cool:

I'll be happy to get 6 years out of the batteries. If I end up routing the oily smoke out the back instead of through the turbo, is there still a need to replace the cdr can periodically?

[M123KT-450]

To my knowledge, the CDR needs the suction to operate ?
I think by routing the hose another way the CDR will close shut ?

Now I did a regular breather on my valve cover but that vents into Atmosphere.
But if you put a barb in the hole you could plum the smoke steam oil ect any place you wanted it.

Where is the ECM fuse? Do I know when the engine has oil pressure by watching the dashboard indicator and what is the proper oil pressure to get to?

[grancito]

On my 94, the ECM fuse is behind a door in the dash, low to the left of the steering wheel. You will see the oil pressure on the gauge, should be about 40 psi. It will need a few turns after there is pressure to refill the lifters.

Man, I wish I was more of a mechanic.

[grancito]

Don't worry, with a bit of time and experience, you will be better than one.
