Cost to Repair a Honda V6 Engine that Jumps Time

The original oil leak was the oil pump gasket. The second oil leak was from a crank seal that was slightly nicked during install (from the keyway on the crankshaft).

The market price for a timing belt service, spark plugs and valve adjust on a Honda J-series V6 is about $2500 in this area.

This one is p/s pump #3 (the last two were Cardone, go figure). The trans is still okay but does display some signs of delayed engagement.

It happens when the friction lock between the head and block gets broken and due to core shifts the bore is no longer round. With seated rings and crosshatch, the engine can not reseal. Rod

I have not had this issue, but I only recently began doing major repairs. This car was completed about a week ago. The last head job I did has 4k miles on it without any issues.

The ~$550 number for parts on the used engine included hoses and a t-belt kit. The mounts are fairly new (and OE) on this car.

Repairing the existing car is way cheaper than buying a new car. If the car is liked, does what the owner requires of it and isn't rusted to death, why not fix it? Who cares what it's "worth"? It's value really only comes into play when you're looking at selling it or dealing with insurance claims. Naturally every auto comes to a point where it's not feasible to repair it and there is greater value in replacing it, but for a Cali car with not a huge amount of miles on it, more than likely it still has lots of serviceable life.

On an semi-related note, Honda needs to sell a "valve-grind" gasket kit like Toyota does. Or even a complete Engine Overhaul Gasket Kit. It would have made the parts ordering process A LOT easier (and probably cheaper).

If you were to chop a link on a new chain and measure it, and compare that length against a "stretched" chain, you'd find the stretched chain measures longer. The term though is a misnomer. Nothing in the chain actually got longer. But if you look at the chain, it is essentially a bunch of pins and plates. Some plates are press fit to the pins, some plates are loose fit. Over time, those loose fit holes become larger. Or the pins themselves have a groove worn into them. Either way, the chain gets more sloppy, and longer. Eventually the tensioner can't keep up. Now this issue is rampant on bicycles, as the chain is exposed to the elements and wears out rather fast (especially if not maintained). But when they wear, they typically damage cassettes and chain rings. For some reason I've yet to hear of this problem on engines--but I'm no mechanic and have not replaced a chain just yet. But when a chain stretches it likely (always?) damages the sprockets that it uses.

Ford has them and it is nice. What isn't nice is when they update different parts in the kit to not include head bolts and forget to list it.

GM 3.6 is just one example, there are others, part of the fix was a shorter OCI.

It was user error. During an oil leak diagnosis, the engine was accidentally allowed to run without the crank pulley being installed. Clearly this was a terrible idea since the crank sprocket is keyed to the crankshaft.

Ouch - that was a painful mistake.

Yet the idiots at GM dropped the indestructible 3.8 in favirtually of the cam chain eating 3.6 and the awful 3.9. Rod.

The problem with the 3800 was its physical size, it was a big, heavy and wide engine for its displacement and wouldn't work well in the later body styles which demand weight savings, great engine though.
