Cam Bridges/caps Stuffed

Hi everyone, i just finished putting a new head gasket on my RB25 and have run into a bitch of a problem.

Ill just explain what i have done so we're all on the same wavelength

As i was bolting the exhaust cam back into place i found that one of the caps/bridges has the bolt locked in it some how. Its the E7 cap which is the very back one on the exhaust side. I have tried EVERYTHING to get the f**ker out with no luck, ive tried WD40, silicone spray, that freeze spray stuff and no luck. Then i tried putting it in a vice and tapping the bolt out. (by this stage i was pissed off and not thinking straight) By doing this it has scored the edge of the cap and is now un-usable.

My question is, i have heard that each cap HAS to go back in the same spot in the same direction as they kinda bed in with the cam and if put back on incorrectly can seize the cam. What can i do? can i just buy one off another RB25 and use that?

Please help, this is the only thing preventing me from getting the motor in the car and running!!! . . . until i run into more problems of course :S

Cheers

Post a pic of the cap mate, how bad is it? You may be able to just file the burr off.

You are correct in saying that the caps need to go on in the exact spot - that is the exact position as to where it was machined, and to maintain the front marks and/or keep the numbers facing the same way as the front cap. Have seen way too many people get it wrong and chew out there cams and caps and spreading crap through out the engine.

worse case it can be welded and line bored, i was building and engine for a mate and his disintegrating big end bearing destroyed most of the cam and journal on one side of the sr head and i got it fixed... anything is possible.

Hold the cap in a vice with soft jaws, heat the cap up and unwind + tap the bolt using plenty of lube.

Carefully deburr it and give the bearing surface a LIGHT rub with some wet/dry and crc.

Line boring these heads is costly, (im an engine Recoér) Worst case scenario is get another cap (i have some spare) and then polish/sand the bearing surface until the cam spins - then sand down the parting face of the cap until there is around .0012" -.002" clearence. Have done it many times. Just be carefull!

    • Its also very clearly made to take business away from https://theskylineshed.com/ which is legitimate and even has a physical address.
    • The 'About Us' got me ..  I added something to the cart and clicked 'check out' and none of the payment options in the footer (ie those with buyer protection) were available. Stay the hell away from this one.
    • No. Not true for any non-GTR R32. I think even the GTS4 has the GTSt knuckles with eye type lower shock mounts (as opposed to GTR fork lower shock mounts). The only R chassis in which something like the quote claim is true is the R34, on which the turbos have the fork type and the NAs have the eye type. **Edit: Actually I reserve the right to be wrong about the above statement. It might also be true on R33s. My memory on those shitboxen has faded too much.
    • It's a scam. It has all the telltale signs: - The "business" doesn't have a physical address or really any kind of information listed - It's using a generic online store website template - The prices are ridiculously reduced. To good to be true cheap - Everything is in stock and can be ordered in any possible combination   I've seen a few of these for other products as well. Things like sunglasses for example. I'd say stay away from it! And maybe reach out to the real theskylineshed and let them know this exists. I doubt there is much they can do about it, but still.   I don't know if they would actually take your money if you ordered something. Or whether it is just for collecting credit card details to scam otherwise. I'm not game or stupid enough to try it.
