2.2190d85 I can't belive how hard that was/glowplugs

Thanks for the comments on the glow plugs on an 85190d2.2
I took off the air intake to get to them and WOW...it was a lot more than four bolts...more like 20 and half of them really hard to maneuver. (a little exagerated)

One of the glow plugs was striped but nothing a 12 mm boxed end wrench couldn't take care of. I replaced them all and coated the threads w/ anti seize...

I'm soaking the intake manifold over night to clean in the morning and put (hopefully) everything back together...

I feel like a total diesel mechanic....grrrrr...covered in oil..I could see the valves and they looked pretty dirty...any recommendations...yelrah wish me luck!

yelrah32,

What did the intake manifold look like inside?

Do you an EGR valve on your engine?

I am assuming you have a positive crankcase ventilation system that sends oil fumes from the valve cover into the air tract?

I have the intake off my 350 SDL and it was awful ... have had it at a machine shop for a week ... they soaked it and used cleaner device internally, but we only able to get part of the material off ... the combination of EGR and oil fumes had built up huge deposits - as much as 10-20% blockage at one spot.

You might consider routing the oil fumes to under the car ... it was one of the many recommendations I have received in addition to "fixing" the EGR.

air intake manifld/ glowplugs

I do have a positive crankcase ventilation system, if it's the black tubing that comes out of the valve cover and to each of the intake manifold pipes almost to where they attach to the block. Are you suggesting that I block the hole in each pipe and route it from the top of the valve cover or plug the hole in the valve cover and route it from each pipe to under the engine somewhere???

I too soaked the manifold all night at a motorcycle shop across the street. (mineral spirits, ran on it continuous all night) I didn't have severe blockage as you had but it was pretty caked in there. I scrubed it pretty good though. I got it all put back together and everything seems ok.

The reason I went thru all this was because it was taking so long to start when cold. I'll see in the morning if this fixed the problem.

Get this, I just had the alternator rebuilt; aparently it was the original alternator from 85. The guy had to rebuild it twice. I think the alternator problem is from the car taking so long to start, therefore draining the battery. thanks for the reply yelrah

Your PCV setup is different ... if it goes directly to each runner and thence to each cylinder, it probably won't build up as bad as mine, so you should leave 'em like they are ... did not sound like yours was all that bad.

If I were to clean all mine intake manifold, crossover and fittings, the gunk would likely weigh 1/2 pound.

How is Gainesville ... went to school there once upon a time?
