Hello,

I have been following all the different threads in this site with a lot of interest!! ;ol; I have learned a lot from all of you, now I need a little bit of help.

I have been dealing with a leaking valve cover gasket, which I have removed the valve cover and I have cleaned up. I also found that the valve cover plug (where the distributor used to go) has been leaking for a while, so I decided to replace as well.

The problem that I am presently having is that I have already broken two T40 tamper-proof bits and the bolts are not budging at all. I am following the standard rotation here (left-turn to loosen), but nothing happens and the bits keep breaking.

Has anybody run into this problem? I have consulted the WIS about this and nothing has come in regards to the procedure to remove this plug, which is straight forward.

Do I need to apply heat to head to loosen these bolts? I would appreciate your opinions about this, since it is driving me crazy.

Looking forward to your responses.

Thanks

Hmmmm...I'd assume they have thread locker on them, and given expansion and contraction they've seized up quite well. My $0.02 would be to give end of the bit some swift taps with a hammer, shock the threads a little.

What are you using to turn the bit with? I think I had to use at least a 3/8" ratchet on mine since they were so tight.

You know, this is the first time ever that this valve cover has been removed in this car. This is also the original plug, and I don't know if thread locker was applied on these bolts at the factory.

I am going to go get a new bit and I am going to try what you are recommending. I tried to hit the bolts only with a dead-blow hammer, but nothing.

What type of hammer do I need to use here?

I will also report back when I take this off, and they are going to come off!!!

I started with a 1/4" drive, but there is no leverage at all; so I moved to a 3/8" drive with a 1/4" adapter.

I even used an impact electric gun and no luck. I am thinking of using a 1/2" air impact gun to try as well. Do you think that might work? I am going to "wacked" the bolts with the bit on as suggested.

Just knock the plug out and tap the new one in, leave the bolts alone.
Seconded, the plug is not a pressfit, it just slips in with a big o-ring to hold it in place.

When I bought my car the plug was leaking and I slipped it out by hand. The o-ring was hardened to the point I couldn't pry it out of its groove. I put some black RTV around the old, hardened o-ring and slipped the plug back in, and haven't had any leaks since

If you'r breaking the bits than I would say try to find a better quality tool which won't break. When I did this I bought one of these from Lowes and did not have any issues. Not saying Kobalt is the best brand but maybe find something of higher quality.
