$6,000 for 5.7 engine work?
 

1998 Baja 5.7 248 hours. Thought I had a starter problem. Mechanic came out and there was water in the cylinders 3 of 8. Says he needs to pull the engine, machine it, and rework the heads. Will put a better cam and I think roller rockers for 6k. Said this is the only way to do it right. With out tearing it down he doesn't know if it's a bad intake manifold or heads but either way the block should be machined. Does this sound like my best option. Wasn't prepared to drop 6k.

6K :eek: Seems high to me.
You could buy a brand new engine installed for that.

Hell buy me a plane ticket and I will come down and install it for you :drink:

I personally would pull the heads and see if I could find the problem. 248 hours is not that much.

$6000 is WAY too much. You can get a brand new crate motor for a lot less than that, something like 3600.

You can buy a mildly nasty 383 stroker for 6000.

Ask him what cylinders were wet. If they all 3 were on one side of the motor, it is likely it is an exhaust manifold/riser issue. I am fighting the same thing right now.

Found this link from old post at other site, 325HP complete for 3500:

I may be in a similar situation right now too. Although, as of right now, I'm not even sure what's wrong with the engine exactly. 1999 5.7 Mercruiser with only 182 hours on it :(

I've seen that motor listed above for $3500, but isn't 325hp pushing it for an Alpha lower?

Welcome to the OSO, I recognize you from the 'other' forum. I am J388 or something like that over there.

Yes and no, depends on how you treat it. Traviss here is pumping 550 HP :eek: thru an Alpha, with zero problems. I will be around 370-400. The 'sane' rule of thumb I hear a lot is 350hp.

The consensus here w/high HP small blocks is to take it easy on the drives, (no full throttle hole shots or air time) use a drive shower, and keep good fresh lube in it.

Big blocks (454's, 502's, etc) aren't recommended, because they typically have more brute (lower end torque).

Well that's good to know! I don't think I'd go much beyond the 325hp anyways, as that would move a 19' bowrider along pretty well as it is :)

:eek: $6K is a lot of cash. I also have used the above engine like Joe with good customer results. That wouldn't be a bad deal for you if you have a 260 hp or less. For 6K you could get new exhaust and hoses plus rebuild the t-stat housing and replace the coupler for that!

As usual, just my .02.
