    1994 Caddy N-star removal 010.jpgUPDATE:
    I pulled the right head and discovered the engine hadn’t been torn down before. (The one owner, AZ car has 117K miles and has sat on blocks with bat removed & gas drained in a corner of my shop since 2007). There were some fluffy black oily deposits on the piston crowns that cleaned right up with a gentle brush. The bolts on the other hand…I don’t know what to think. 1994 Caddy N-star removal 011.jpg1994 Caddy N-star removal 012.jpg
    A friend, whom is a machinist, has offered to help me with the block tapping and is also modifying a “power steering pump pulley removal tool” to fit the “left head cam mounted water pump drive pulley”. The alignment dowel part of the tool is too large a diameter to fit so he is turning it down and shorting it a mite. I’m anxious to pull the left head since it is the side my local Caddy dealership diagnosed with H/G issue.
    I stocked a Felpro upper-end gasket set this weekend, Thanks O’RAP. I’m planning on ordering a set of head fasteners today from…..Wait for it........CCC!

    Using timeserts? A timesert kit is 300 used. Sell it for 300 when ur done. Don't need no special tools from machinist friend to tap block correctly. Use the timesert kit

    Lets see.......
    Buy used tools off ebay and resell them later for the same $300? Plus add the cost of serts? $$$ And still got to drill and tap? Don’t forget the set of new head bolts $$$
    VS
    STUD THE THING (TKSCCC)
    The only special tools I need are drill bits and taps for the specific fasteners I’ve chosen.
    And wouldn’t I need them for the sert method anyway?
    My machinist friend is providing his experience with alum. And is modifying my P/S pulley puller to fit the cam pulley. The only tool that he might custom fab would be an alignment fixture and I guarantee it wouldn’t cost anywhere near $300.
    Therefore…..
    No timeserts for me thank you.

    IIRC, the TimeSert procedure has been superseded by the BigSert procedure.

    And there are 3 other fully acceptable alternatives out there right now - 4 if you want to get creative with ARP studs and others' inserts .......

    Re: Anyone that has pulled an N*? PLEASE! I need some advice.

    The left head came off yesterday once I removed the pulley off the cam. BTW the modified puller worked great. (Thanks Greg)
    Every bolt cracked loose except the two lower ones at #8. They lifted out easily, complete with alum threads. Further inspection reveled the head gasket had a hole in it just inside the water inlet port. It appears turbulence from the W/P pushing coolant into the head eroded the gasket material between block and cylinder. This allowed fluid to reach the bolts promoting corrosion thus IMO causing the thread failure which compromised the seal at the cylinder. Escaping super hot gasses under compression super heat the coolant to boil over temps, and fast. No white smoke, no consumption of coolant and no contamination of oil. The things normally associated with head gasket failure.
    I don’t care what coolant you want to use, they all will promote rapid corrosion between dissimilar metals when exposed. And ya, excessive forces due to engine mounting bracket attached to the head may have contributed. Just attaching a lifting sling to that corner of the engine when I lifted it out of the car may have contributed to the pulled threads for all I know. But that hole worn through the gasket IMO is the culprit.
    Anyone else seen this eroded gasket condition?
