So um. I may have to pull a head. Hoping to get advice from you all. If youíre familiar with me youíll know Iíve had issue after issue with exhaust. First EGR, The crossover that took ages to seal. Once that was fixed I still heard leaks and found one by cylinder 6, EGR had sprung a leak again and the downpipe flange gasket.

Got that all done and was so fed up after 2-3 weeks of being out under the hood til 3am 5 days out of the week I grabbed the biggest ratchet I could find and wrenched them [censored] down.



A few days later I snapped a stud after losing all common sense due to sleep deprivation, frustration and arguably hunger.



Spent close to 7 hours pulling it out with an extractor followed by a hammered on 1/4 in socket and an Allen wrench. Started out plugging exhaust ports but rags kept falling out so I said [censored] it. Have spent most of today using magnets, air and my fingers pulling out fine particles. Anything from dust sized which I couldnít feel between my fingers, to dirt sized which felt no different than some particles I get in the bottom of my oil catch pan, and the largest bring a few human hairs thick - 1/8 inch long.

This on the number 2 cylinder which appears to be closed.



I found more in Cylinder 4 which is a good 4-6 inches away from #2 but the bad news is that most likely means itís open partially if not fully. To make matters worse the brass tubing is on the compressor is snapped from getting hot and making contact with a solid object. (Iím obviously a bit heavy handed). So Iíve been using keyboard cleaner on the #2 cylinder, thankfully havenít blasted #4 yet.

Soooooo...... big question is how likely is Iíll need to pull the head given the size of the particles? =\

Blow it out with an air gun then pull the plug on any cylinder with a valve open and blow it out with the gun before cranking the engine. It will be okay.

Why didn't you just tape over the hole with painters tape?

You're thinking in reverse.

Blowing is not the answer here.

Sucking is your answer.

I'd attach a small hose to a shop vac and suck all that out.

Take out the spark plug and crank it over a few seconds.

So these are bits of the stud? If so, they are steel and will be picked up with a magnet. Get your telescoping magnet and run all around in there and you'll get most smile

Vacuum is good too. I would not pull the head. Just reassemble and light the kitty laugh

Yes theyíre off the stud. Mostly filings but possibly some larger pieces from using the fluted extractor and hammering on the socket. Iím opting for the vacuum method simply because I have no way telling which valves are open or closed without pulling the valve cover or renting a borescope. Compressed air runs the risk of blowing the stuff into the intake. I doubt the air in can I was using had enough pressure to blow anything much farther past the valve.

Cylinder 2 looks closed but 4 and 6 are sitting lower according to my fingers of I stick em in the port. Just gonna pull the spark plugs and take my time using plastic hose affixed to the end of the vac hose to clean each rear cylinder and exhaust port out.

Quick update. All 3 rear valves are open. Pulled the #2 spark plug and found penetrating oil on it, along with the valve being clear of ash deposits. I first used PB Blasted then moved to a mix of mineral spirits and ATF. If itís on the plug then the penetrating oil moved past an open valves and is probably on the top of the pistons and areas of cylinder wall closest to the exhaust valve. Unless I can find a way to seal off the intake and exhaust ports for each cylinder to apply vacuum Iím cleaning Iím seeing no option but to pull the head.

You cant have the intake and exhaust open at the same time. If the particles got into the cylinder through the open exhaust valve there is no way it can get in the intake unless you turned the engine over which is a no no.
100-120 psi down the plug hole with a open exhaust valve will blow the garbage out, if you didnt disturb the engine then just use some brake cleaner to clean the oil off then blow it out.

Vacuum through such a small pipe isn't going to get into all the places, you could hold the sshop vac hose on the exhaust por and blow air down the plug hole. Air in a can isn't cutting it.

I understand that but there is a small overlap during the intake stroke in which both valves are open and Iím also running high lift rockers which exaggerates things quite a bit.

The way I understood it the exhaust valve was open. Try a long flexible magnet as someone suggested.

It is open and I grabbed a flexible magnet from Loweís today, however the valve is not open enough to insert anything into the engine from the exhaust port. Iíve calculated .464 lift on the exhaust maximum but I can even see into the cylinder around the valve. Even with magnets, air, and vacuum I donít feel confident that all debris can be removed without pulling the head. I can do it myself for about $150 for gaskets and bolts. Made sure to buy shop rags and spray a gasket as well.
