Got a new valve cover at the junker.. didn't bother painting it just going to wait until next summer.. so the story is i just replaced my old valve cover with the new one i got but i didn't wait for the engine to cool down.. i took out threads in about 3 bolt holes.. man now the valve cover won't tighten down.. anyway i can fix this? thanks

fyi car is a 94 civic coupe, with D16Z6 swap.

 

WOW....never heard of that happening. Sorry but i have no ideas except SWAP...LoL.

 

you could just retap the bolts to the next size up

 

^What he said or new valve cover. The world is not going to end.

Try slightly longer bolts first. Many Honda engines have threads that are longer than the OEM bolts.

 

Just get new bolts at the stealership. Here are your part#s

Wait, you stripped out the threads in the cylinder head? Well I guess my suggestion won't help.

 

Yeah..any other suggestions? lol

 

Jeebus, 5.32 for a BOLT?!

Steal 'em from the junkyard lol. I always walk out with a pocketfull.

Can you see down into the holes? Are the threads missing? How much did you tighten them? They're only supposed to be like 7ftlbs, which ain't much at all.

 

No, I removed the bolts to remove the valve cover while the engine was still hot an i took some threads out in the bolt holes.. pretty much leaning towards getting one of them thread repair kits, anybody know what size i need? so i can use the exact same oem bolts? thanks guys for all the replies.

 

take you bolts to a hardware store. Find the nut that fits, and you will have your size. According to the parts pic I posted above my guess would be 6MMx1.5.

 

there is a how to on d-series.org I believe on making a valve cover stud in stead of a bolt which prevents striping out the head which is pretty common on a d-series. Or a helicoil, but there isn't a whole lot of material in the head casting around the valve cover bolt holes. so the helicoil may not have enough meat to properly bite into.

 

listen to this dude...it the best way to fix your prob

 

can you take the valve cover back off?

 

yes, all it does is replace the threads that you ripped out... it comes in a kit that allows you to use the same size bolt... the threads will be stronger then the stock ones because the the material that they are...take the bolt with you when you get the kit, to match the size

 

Just weld it on...or stick a toothpick in the hole and thread the bolt in...or a glob of loctite, hondabond, epoxy, I don't really care.

 

are they 6MMx1.5 or 6x1?

 

they are gonna be m6 x 1. a 1.5 thread pitch is for bigger bolts like lug nuts and oil pan drain plugs
