I am currently working on a marine 454...on the exhaust manifold is a heat riser and over the last few months or years it has leaked sea water all over the block and starter...I was doing a tune up for the owner and upon my pre inspection I discovered the #5 cylinder plug wire was off and the spark plug had rotted out of the threaded lower quarter....now I must remove the Exhaust manifold etc..to fix the problem...now I have rust build up all around the bolts and when I looked in the manual it calls for loctite on the threads and it made it impossible to remove the bolts....I tried everything I could think of...I used a socket for stripped bolts, I tried to manually spin the bolts with a hammer and chisel....I am now thinking of a grinder to remove the bolt heads but wanted some advice before I do this.....Does anyone have any suggestions?:wall: :wall: :wall:

1994 Saturn SC2, 1.9L, 218k, 5-manual. Now that it's getting a little cooler here in WI, I've developed a weird electrical issue. When I turn the ignition on and start I get a click, click, click, click thing going on. I know it's the relays that are making the clicking noises, but any ideas what is causing the momentary loss of power? When driving I lose the radio for about 2 seconds now and again, some days it seems that is goes every time I hit the clutch and break, other times I can slam the breaks and nothing. I guess the question is do I have a break in insulation that allows the wire to short out, or do I have a bad pcb some where that is breaking a connection when it's cold out? Any suggestions are much appreciated. Thanks. Brian
