Dropped my Blazer off nine days ago at Oregon Fuel Injection. Picked it up yesterday. I had the OEM IP rebuilt. They found related timing for issues. Just over $1600. Runs great. Thanks for all the hard input. With all the clatter I was sure it was rod knock. Hoping I’ll have smooth sailing for...

I decided to drive over to Oregon Fuel Injection to have them verify failing IP. I have an appointment for Wednesday.- The drive is one hour from my home. The service desk guy said he DID NOT have the DB2 829-4521 pump on the shelf. He did say the alternate part in the book is DB2 829-4502 (he...

Drock, I am thinking I can find the same result if I disconnect the supply line to the fuel filter, and replace it with a line from a fresh can of diesel. I'll do a filter swap so only fresh gas is supplied to the IP. Good idea, thanks. I'm off to get a new fuel filter.

OK, I will. I asked because I just installed a new Holley fuel pressure regulator on my wife's Mercury 2v Cleveland. The pressure called for was 3lbs. Having spent so much time under the hood of my blazer, I thought 9 lbs was either too high, or the 3lbs was too low. Injectors vs carbs I guess.

LIft pump? new per TM part number IP? I've never touched it. I bought the rig with 56K on it.

What should the fuel pressure going in to the Injection Pump be at? MY spin-on fuel filter has a gauge on it that is reading 9 lbs at idle- Is this right, or will it cause problems?

So, to update; I am reporting that the knocking has returned. I did not get thru more than half a tank since the knocking went away- now it's back. I checked the flexplate- no cracks; the bolts to the torque converter are solid. I replaced the oil and filter; the fuel filter. No improvement. It...

Things are better. After reading several posts from other diesel owners on remedies for the loud, smoky off idle condition, I decided to try adding ATF to the fuel. I wasn't all that certain that it could help as I just completed a diesel purge with lubro moly, so I expected that all injector...

I have another thread regarding poor engine performance, but I am not sure this question has anything to do with that thread, so I am asking in a new thread that maybe easier to find... if you are wondering about spin-on filter maintenance. This is what I have- there is no provision- at least...

Dependable, new glow plugs 3 months ago as a matter of maintenance. New fuel filter last month. Never used ether or other sprays. I was leaning towards rod knock, but want to DIY as much as I can before outsourcing the bottom end work. I have heard of bad fuel as a source of the knocking. If the...

Yes, the idle circuit does return to a slow idle, it's the noise level that does not seem to come down. Today I switched in 8 NEW fuel injectors. I also shortened the lines and inspected all line clamps. No leaks, started right up. But the noisy rattle persisted- just as loud. I put the...

WHAT! That's CRAZY. This is my first diesel, and I have yet to experience injector failure by that bit of info. Is there a way to check and see which one(s) is to blame?

I'll have to look where I bought the injectors from exactly. But I went to a place recommended on this forum. They were installed 3 months ago. How many have to go bad before they make all that racket?

It has been running swell, no tell tale of impending problems.

What was going on with the lamps?

I changed the glow plugs, the injectors, oil and tranx oil/filters. The radiator does not leak, the fuel filter (OEM) was replaced with the F100M round filter system and gauge. The 300 to the destination went off w/out a hitch. The return trip started feeling tinny, and weak the last 100 miles...

Here is a photo- It's raining, and the hood was against the bright (hazy) sky, so sorry about the pic quality.

The heater core was one of the first projects I got on when I bought my M1009. I posted a few thoughts in an earlier post. The folks on this forum advised to have the OEM heater Core rebuilt by a qualified tech. I needed heat, so I bought an aluminum replacement at NAPA. It came packed in a nice...

Just installed a new underhood liner/insulation pad. I got it from Eckler's P/N 332505- under $50 shipped. Of all the liners I have used over the years, this one was perfect all around. Came with new pins. Came pre-drilled to match all holes. I have not driven it around yet, but will. If I am...

dom1986ck30, I'd agree with all recommendations. I had a slow starting M1009. Slow to start, slow to warm, slow to find gears until warmed-up. I changed the starter- found the PO had been using a 12 volt starter, no bracket. I installed new fuel injector lines and glow-plugs, but still had slow...
