Buddies has an 88 pickup 22re
The other day he went to start it up and it turned over right away but it sounded like diesel, but in the worst way. Almost like some one dropped a few bal bearings into the head so he immediately shut it down and unscrewed the oil cap to find the head was filed with oil. w.t.f. is going on with this thing anyone have any ideas i am thinking connecting rod but that is just best guess:frown:

Monday we will pop off the head and take a look
 
yikes!

somthin broke off and clogged the oil return hole. or, there is sludge in there. or, there is sludge clogging the passages in the valve cover and, just that is filled with oil. i dunno. taking the valve cover off is the first step.

but i think that it would be a good idea to take it aprt tomorrow. in hopes that oil somwhat drains back. so that way, you dont flood the driveway when you take the valve cover off.

did you pull the dipstick?
 
turns out it was a water pump nut floating threw the engine :eek: i will post pics on tuesday when n8 and i get workin on the engine again

yeah please do, as i dont even undertand your post.
 
Ok so what happend in order was this:

At some point someone (im not ruling out me but I dont think it was) droped one of the four nuts holding on the watter pump pully into the oil pan.

That nut then got loged in between the oil pump gear and the aluminum housing around the lower part of the oil pump the nut broke the aluminum housing into small 1/8 inch peices that were bouant enough to float up with oil to the top of the head.

about six little peices of aluminum landed on top of a valve and when that valve opened it droped the aluminum into the piston chamber.

the piston came up and mashed the aluminum chuncks into the head and repeated this process making a very loud scary metal on metal noise (why whe thought a conecting rod had broke)

now there are goudge marks in both the head and the piston from where the aluminum was.

anyone think that I need to replace the piston or the head??? is it ok to have goudge marks on the top of the piston, if not why? same with the head.

also I fear that there is still aluminum in the oil ports that may have not yet made its way up into the pistons how should I go about cleaning everything out??? I thought maybe submerse the whole lower block pistons crank and all into a vat of 4d 40 or some cleaning solution... good idea bad idea???

any thoughts would be helpfull at this point.

thanks guys!

:doh:

(this sucks)

Whoa, something is not right with this!

How can a piece of metal, that is in the oiling system get into the intake?:confused:

Oil gets sucked up into the pump from the oil pan through the pickup tube and then goes to the oil filter. How can a piece of metal that large get through the filter? A piece 1/8 inch in size is very large when you are talking about what an oil filter is supposed to filter out of the oil. Oil filtration is measured in "microns." A micron is 1 millionth of a meter. Oil filters will not let anything that size pass by.

Now, lets just suppose that pieces of the front cover broke off into the timing chain area and then were carried up to the valve cover. even then they could not get into the intake system.

Something got sucked in through the intake to do that damage. You need to be looking for what else may be damaged in this engine.

You need to do COMPLETE rebuild in order to clean out the oil galleys and inspect all of the bearing surfaces.

As for the gouge marks, they need to be smoothed out. If left alone, they can become hot points that will cause detonation problems for the engine and detonation will destroy an engine. Although, the knock sensor would detect this, the computer would make corrections and the engine would run poorly.
 
I was able to take the peices of metal that were being smashed and fit them together lego style to the aluminum just under the oil pump. I asume they were thrown or caried up into the head via the big hole for the timing chain and somehow worked themselves through a valve (the peices were not that big)

anyway I think the idea is to strip the block and soak it in gasoliene for a day or two and then hit the oil gallys with compresed air to get the rest of it out.
and instead of smoothing the piston head im just going to replace it with one of my many spares.

wish me luck :cheers:
 
Yep, that theory won't stand up. No way to get through a valve except from inside the intake system. Not from the oiling system. No way, no how.

A nut in the oil pan will just sit on the bottom. It won't get sucked up. No way, no how.

If it did get sucked up, it would not get through the screen on the pickup. Again, NWNH.

If it did get into the pump and cause breakage, the pieces will not get through the filter. A big NWNH.

Anything that got caught up in the timing chain would have been stripped off by the chain tensioner and/or the chain guide. If something did manage to migrate up that way (this is at least possible) it would just sit in the rocker box. No way to get into the cylinder from there.


If it's in the cylinder, it came in through the valves or was left in there during assembly. If it came through the valve it did so from inside the intake tract.

Nate,

Please post some photos so we can see the damage.

2x on what Mark W said.

Something came in through the intake.

You need to do a complete tear down and inspect everyting.
 
Ya tonight was the first time I was able to get some photos that were worth a damn so later tonight when im on my own computer ill load them up.

Dont worrie about me tearing it down the thing is in peices right now and im scrutiniseing EVERYTHING

thanks guys

p.s. if it were to happen how would anything get from the oil pan or head into the intake?

It can't.

Do you have a PVC valve? It could get sucked up and into the intake that way.... I'd play the lotto before betting on that hapening though......

Beyond extremely doubtful. There's a baffle below the PCV valve. Then there is the valve itself. Not really anyway through there for anything solid. And then the fact that the suction through there is actually pretty small.

Liquid or gas? Sure. Solid debris? Nope.


Mark...
 
I may be asking a stupid question here but why is it inconprehedable that it could have worked its way into a valve through a compression spring and droped into the cylinder on start when it was opened? the peices were sure small enough to make it through the valve seals and the opening of a valve...

and there has to be a way because the aluminum that I found cramed into my piston and head definatly originated from the valve cover below the oil pump.
 
Ok here comes the photos get ready

the red arrow points to the nut that was found in the oil pan. you can see how the head is shiny from being milled by the oil pump.

In this photo the two red arrows are pointing to the peice of aluminum that was making the most of the noise, and I am pointing at the broken jaged aluminum housing that set aluminum peice originated from.

those other two peices were accually a buncha shavings that had been mashed together and were plyable and able to be crumbled into metal chips.
 
here is an out of focus shot of the head

more specifically the dent that the aluminum made in my head

sry its out of focus my camera was not up to shooting that close.
