So... recently I sent in my head to MAP to have some work and bigger valves installed on it. When I got the call about the work to be completed, the salesman said that the tech found particulate metal matter/shavings in head when they were cleaning it. So, he advised that I take off the oil pan to look at what may be down there and possible causes. I took it off and I found a thin metal "pin" piece that was about 1.5" long in there with a few shavings and that looks like it was bangged around. Anyone know what is this and what should be replaced in this case? I really don't want to send the motor back to MAP for a complete tear down and rebuild but if I have to, then I have to. Opinons of what this is and the fix? This can only be no good....

Thanks in advance!

 

no one?

 

was there bearing material in the pan or just that? Doesnt look like anything that would normally be on the inside of the engine though.

 

That looks like an oil squirters that has been owned by piston, rod, or crank. I'm willing to bet you have spun a rod bearing. The clearance of the oil squirters with the piston is very tight

 

yikes

 

Def one of the oil squirters, you have to bend them slightly to clear on a 2.3 setup.

 

Thanks gents for the info. I believe you are right on the oil squirter. I am going to check it over tonight and see if that's the case. If so, is that something that the crank has to be removed in order to fix or is that something that needs to be machined and reinstalled?

 

Take them out and weld them up. You can get them out without removing the crank.

 

ouch that sucks man

 

found the bad/broken oil squirter. From what I can see, doesn't look like it caused really any damage (that is visable at least which makes me scared). When replacing the oil squirter, what is the best way to clean out the thread holes in order to achive the correct torque specs?

 

I'd be more worried about all the metal that has circulated through the oiling system at this point. Bearings need to be checked at a minimum, oil pump and oil cooler if you have one. The reason I say this is if they found particles in the head that means its been pumped everywhere else. If it broke off because it was hit by a rod or piston then its the engine builders mistake or who ever installed the oil squirters.

 

I agree. And I have to think of how to approach this with the builder/company.

 

As a result, here is a short video of the underside of the piston that the oil squirter broke off in:


More problems = more $$$. Welcome to the world of high HP cars. I still love it.
