Ok my engine is on its way out, the lack of compression in 2 cyls, the noisy lifters and now the timing chain sound a bit lose.
I have 2 options to get it all going well again
1. find an AU or similar engine that is already built for gas (ford gas setup) and drop that in...
2. Get my engine (XG 4.0L) rebuilt with upgrades to accomodate the gas a bit better. If i do this I will upgrade to the point that it will be a gas-only engine. ie rebore, pistons, rings, cam, head shave, valve stem seals, valve seats, maybe a port cleanup and re-tune.
What do you think is the better option?
How much should this be costing me all up?
Thanks in advance
