Baja 38 special model 2000
 

I just bought a Baja 38 with two 502's MPFI.what is considered a normal oil consumption running at cruising speed.

Re: Baja 38 special model 2000
 

A quart every 5 to 10 hours.

What kind of oil are you using ? What weight?

I had the same boat with the same engines for a few years. It did use oil, but I don't remember it being alot. Seems like I added a quart or so every tank full. I ran the sh** out of that boat and had very little trouble with it. I do remember replacing some of the cheap hardware that would break occasionally. It did not have a single stress crack in it anywhere when I sold it. The guy that bought it went over it with a fine tooth comb trying to find a crack. Didn't find any.

i did have to replace the internal exhaust flaapers. Drove me nuts trying to isolate the noise. You could only hear it when the switchable mufflers were on. I even replaced the gimble bearing before I finally figured it out.

I use 20W-40, and I use approx.1quart per tank.
One engine smokes a lot ij idel after a hard run, my mechnaic says it is only water vapor which might be correct becasue it doesn't smell like burned oil.
Water temp close to 180F, the other engine runs at 170F.
Any thoughts about it,
thanks

502's do use oil. It is a known fact.

I had one that was about as bad as yours, about a quart for every tank of fuel.

A couple of things I learned to keep it from using so much.

1) Try Valvoline Straight 40 Weight Racing Oil.
That made a big difference.

2) Make sure the engine is up to operating temp before getting on it, or even coming on plane.

I was told that you are simply getting a lot of blow bye on the 502 until it is up to operating temp.

Don't worry about it, they all do use some oil.

By the way, Nice Boat!

How many hours on these engines?
Do the hour meters match the ECM scanner?
Do you actually HAVE blowby?

Re: Baja 38 special model 2000
 

the engines have approx.360 hours and they match with the scanner.
I think I must have blow by because there is no leak

Thanks for the tip and I do enjoy her

Check for blowby by removing the oil fill cap from the valve cover while the engine is idling. With the back of your hand feel for pressure blowing from the opening. If you feel nothing, chances are you do not have blowby.
I had an old, tired small block in my Camaro that had blowby so bad, you couldn't add oil with the engine idling. It blew it back out the funnel! (Before you Ford and Mopar guys get on a roll, this 305 SBC had 265,000 miles without a valve job!).
