I'm a member... GUT MY PRECATS!

Anonymous · January 20, 2005, 15:00

I'm sure I can guess what kind of response I'm likely to receive here but as the old line goes "if you don't ask, you don't get".

I am getting more and more concerned about the precats situation... mainly because I can see it's going to cause a problem for me eventually and I'm not mechanically minded enough to gut the dang things - even with all the guidance on the forum. Can you see where this is going yet? s:)

s:)

Is there ANYBODY out there who's already gutted their precats, would be willing to gut mine?

For a fee obviously! s:D

s:D Not sure what the going rate is but if you want to earn some cash from my poor old pocket then now's the time to speak up!

So then.... Anybody? s:?: :?: s:?:

I have that post saved as a fave, and i reckon i could do that.

However, its all the other posts about rounding off bolts that scares me.

It's worth keeping in mind that while there's a risk of snapping a stud or rounding off a bolt during the removal of the header, the entire point of the job is to prevent catastrophic engine failure. A damaged fitting can always be dealt with. Here are some tips I found for dealing with such a event:

--------------
1 Just heating the stud to red heat and allowing it to cool is sometimes enough to crack the rust and allow it to screw out.

2 Welding a nut on the stud and turning it back and forth seems to break the rust to powder and allows it to come out. In some cases the studs are so thin it breaks them off.

3 Drilling out is the next method. Taking care to centre the punch will save a lot of work later digging out threads from an off centre hole. Done correctly, the remnants of the threads can be peeled out in several strips.

4 The final solution is blowing it out with the oxy torch. This is a last resort as it is possible to melt the cast iron and destroy the threads. It also makes the cast very hard so that it is difficult to cut an oversize thread. Drilling a hole through the stud first gives a thin edge to start the torch on and allows you to burn the thing out quickly without overheating the cast. Digging out the old oxide is not easy - use an old phillips screwdriver sharpened to a point and a small hammer.
--------------

Tip number 1 worked for me. Also, you can minimize problems by using liberal amounts of bolt loosener on tough customers and give them 24 hours of soaking time. Cheap tools will also increase risk. Preferred brands in the U.S. are professional-grade Craftsman and Snap-On wrenches and sockets. They're pricey, but they give you every possible edge against rounding. Look for 6-sided sockets for maximum grip and avoid 12s and 16s. Prepare for the job, go slowly, be methodical and virtually anyone can pull this off successfully.
