I am trying to unscrew the 3-14mm nuts that are screwed to the header pipe. I am in the process of changing the oil pan gasket.

I used a 14mm deep socket + breaking bar and it started slipping. I dont want the nuts to get rounded. Is there a way or another type of socket to loosen it?

Thanks

 

try spraying some wd40 on the bolts and let it set for a couple hours, a day would be better, should help
good luck

squirt some PB Blaster on them and let it sit for a while. If that fails and you can't get them off w/o stripping them, check and find the the next smaller size in the SAE equivilant socket and knock it on there and bust it loose.....

That or just take a torch to it, get it hot, and then unscrew it.... Or just get the engine nice and hot, then try...

 

Hit that **** with a hammer to knock off any loose rust before you spray it, I always do...

 

"PB Blaster" and time. maybe impact wrench.

 

pb blaster and let it soak

 

we did all that and more to my friends prelude we ended up having to cut them off...

 

they sell sockets made for stripped bolts, id definately invest in some....theyll save your life over and over

i like where his head is at.

 

Just go at it with a grinder.

If your car is anything like mine was those bolts are not coming off.

 

Update:
Thanks to all of you. I sprayed WD40 when the engine was a little hot, had to remove the heat guard. 6 hours later managed to unscrew it with a breaker bar and some extra muscle. This weekend I will change the oil pan gasket.

I dont want to open another thread but I have a few questions.
1)The PCV valve is located at a wierd place how do you remove it . Do you have to pull the hose from under the intake manifold and then pull the PCV from top? or - - -.
2) I want to degrease the arrea around the engine. Is there a good product for this?

Thanks again

Dan
