    Caddy down, Caddy down!!!

    My Brougham jumped time last week. I'm thinking of doing the work myself. Shops around here are talking $400+. I want to save the money so I can throw in a new water pump and thermostat while I'm in there. Any tips master techs?

    Jumped time? Wow you must have been doing over 88 at least.


    Do you have, a timing light? If not, a remote starting switch (or a helper to turn the key)?

    If you mean the actual clock on your car, and it's something electrical try disconnecting the battery on your car overnight and seeing if it resets some of the circuitry.

    Olds 307 timing chains are fairly easy, the only "issue" is the oil pan, you will need to loosen, but not remove, most of the them to do the front seal right so it won't leak. The books says to remove pan, unnessary, but you do need it loose.

    Just take your time and pull the accesories away (ps, AC, alt, fan, etc) and then waterpump (have coolant already drained, force as much out as you can with shop vac to prevent any from going into the oil pan) remove water pump (good idea to replace bypass hose while it is off) and then pull front cover.

    Are you sure it jumped time, or did it lunch the timing (cam) gear all together? Mine did on my 76 Olds Delta 88. Was running, it surged in power and died, not to be restarted. Pull dist cap and crank, rotor wasn't turning.

    Well, it died and wouldn't restart, just spinned as if it wasn't getting gas or wasn't firing. Then it started to backfire while trying to start it. It was also blowing out puffs of soot when it backfired. My first impression after the backfire was that it had jumped time. I had a mechanic friend of mine take a listen and he also felt that was the case. Just before it died, it was stalling like it was going to cut off. Did that maybe twice before it quit.

    If it is the timing it won't be too serious, just hope I didn't misdiagnos. Hate to spend all that time to no avail. Cost is very minimal, around $20 for chain and gear, another $25-30 for a new water pump and a few more for a therm and bypass hose. Might as well replace them while there off. $65 tops, unless wrong prognosis.

    I had a little Monza with the 4 cyl "Iron Duke" I lost valve timing also. I pulled it apart (valve cover, timing chain cover) the chain and gears looked fine, tension was good, valve timing was shot. I was confused. I guessed but never verified that the shear pin on the cam shaft and gear likely sheared allowing the gear to spin somewhat on the shaft. I didn't bother investigating further as I didn't feel it was worth repairing so I junked it.

    What does that have to do with your situation? Maybe nothing, I don't know but it's late and I thought I'd share it. .... .... ..

    I must be getting tired..

    MEDIC!!!! MEDIC !!!!!! CADDY DOWN !!!


    kev brings up a good point , you may want to check the key down there if it has one (hey nodih does it ?)

    As for that monza , that was a easier fix then what kev went thru . you see they made a monza fiaxall tool , lots of engineering went into it and it was made by the moltov company , the cocktail proudct line , flaming edition , very quick and efficent , even came with the phone number to the insurance company to inform them about this myster fire caused by the fixall tool ....very neat , to bad liability lawsuits forced them to close there doors in 1988

    I hear tell Ford did them one better though, they had theirs built in. I beleive the Pintos were the first to sport the device. They didn't gain too much in popularity though as they had a tendency toward premature ignition?

    Hey guys, forgot to tell you the Caddy's up and running. The timing chain fix was successful. Also had to change the rotor button. Overheated while trying to start it I guess. Damn thing was in pieces!
