I bought my dream car a 1989 FJ75RV TroopCarrier a month ago. It had driven well for a month and I have replaced all fluids, spark plugs, adjusted valves, and timing. Ready for re-registration next week... so I thought!!
3 days ago it just simply died while driving. No mechanical noise/clunks etc. Pulled to the side of the road and when trying to start the engine spins high/lose. As if no spark plugs are present. Towed it home.
Since then I have read about timing gears etc. and read few experiences in this forum such as they can be lose 10deg. etc and checked the following:
- The valves and distributor rotates, which eliminates timing gear failure issues
- Can see that at TDC mark cylinder 1 valves are lose and 6 are tight as per FSM
- Did compression test on cylinder 1 and showing 0. Put tablespoon of oil and still 0
I will do leak down test to see where the air is escaping. But I am a bit puzzled why no compressions at all on ALL cylinders at one time? I was "hoping" it was a simple timing gear failure. And burnt valves do not happen all at once. Any clues where else I should look at? I am new to this engine.
