Well, I went over our freshly acquired '95 XJ w/201k miles last night. 2.5L I4 w/AX-5 manual trans.
The motor has 3 bolts missings on the intake/exhaust manifolds. 2 of the bolts are on the very ends of the exhaust manifold, which are actually studs.
The one missing bolt, the threads are evident, so hopefully its clear all the way down the bore. Has anyone had a manifold bolt have the tip break off and leave it down the bore? I've never had it happen, if they break its at the surface or farther outside, so hopefully thats the case.
Its hard to see inside the bolt hole on the exhaust manifold, but a little probing seems to show that it ends at the head surface, considering it pretty common for exhaust studs to break, it appears the studs are probably broken off at the head.
Any tips on removing broken exhaust studs out of the head, broken off at the head?
I plan on;
*Pre-Treating the bolts and broken studs with penetrating oil for several days before the job.
*Remove the intake & exhaust manifolds, to get access to the broken studs.
*Drill a Pilot hole in the center of the broken studs, then a larger hole deep enough for an easy out.
*Try to turn them out with an easy out.
Any tips to add to that or a better way? What do I do if this attempt fails?
