I was replacing some broken exhaust manifold studs on my 91 Galant VR4......2.0 Liter 4g63 AWD Turbo.
Behind the center exhaust stud is an oil drain passage. RTV must be put on this stud or you will get an oil leak.
This center exhaust stud was broken and I needed to use an easy out to get it out. I was able to get the stud out and needed to tap the hole. The tap broke when I was backing it out.
I am sure that I will have plenty of metal shavings from the initial tapping and drilling or even pieces of tap (hardened steel) by the time I am done getting the tap out.
My enthusiast forum essentially suggested that I shouldn't worry too much and to just drop the oil pan and spray some valve clean in the valve cover. It was mentioned that the shavings are in an area that is not a pressurized oil passage just a drain oil passage. Never really stopped to think about what that meant but it sounds good to me. (Guessing that this part of the oil system has nothing to do with the oil pump).
I just had my turbo rebuilt so figured that I would take care of the broken exhaust manifold studs at the same time. I don't want to wreck my new turbo or my engine with these chunks of metal!
I figured that I would come here as well to discuss as well since we talk alot about oil here.
What steps should I take to get the metal out?
Would the above be sufficient?
Thank you
