Challenge: Engine Diagnosis

[SkiprJohn]

Oops its a W46 and I know nothing about it. Disregard my last.
kind regards,

The 4-108 is a Perkins based. It was either the 107 or 108 that had sleeves. Mine is a W-46 or Mitsubishi 4DQ5.


On a cost note the complete gasket kit through a Westerbeke dealer is $1200. Through a Mitsubishi dealer in town here it is $388. Now I will load up the engine and take it to an engine machine shop I know, to see what work needs to be done. My feeling is while I am still employed, I should freshen the engine even though there is only 485 hours on it...Stay tuned.

Also, the perkins 4 108 has sleeves.

I stand corrected...The gasket set from Westerbeke is not $1200...it's $1700. Now, I realize this probably includes the marinizing gaskets but come on! Now I know why Beta marine started up.

That is simply incredible! They must be gold plated.

.........Even the dealer laughed when he quoted the prices...by the way, one piston was $284. He was very understanding when I told him..."Why would I ever want to buy a Westerbeke when the parts where so damn expensive. I had one of the dreaded Volvo 2003s a few boats back...a real POS that one was. In 1990, a starter motor was over $600. I'll tell you, there is a reason Yanmar dominates the market.........
1) Reliable engines
2) Good dealer base worldwide.
3) Reasonably priced parts.

G'Day CS,

Wow -- those must be gold leaf gaskets!

FWIW, a few years ago I was needing a head gasket for a BMW D-35, and their price was something unacceptable to me. Just for a reference, I went to a place that made custom gaskets (don't remember the name, or even where we were at the time, but it was in the US). To my surprise, their price was less than half of the BMW price.

Now, many gaskets can be hand made from appropriate gasket material, available from industrial supply houses. The more difficult ones, like head gaskets, can perhaps be sourced from places similar to the one I found.

Can't promise anything, but when the numbers get as large as quoted to you above, some research is in order!

HOpe that you can find some better way!

Cheers,

Jim

I found 90% of what I need through a Mitsubishi dealer which is the engine base. He even stated that sometimes Westerbeke has a proprietary on engine parts but not in this case. I know some "marine engine manufacturers use a Kubota diesel engine and I'm sure it is easy to find parts for them.

It says 4DQ5 on the block. I think it is tractor.

$1,700.00 vs $400.00. You must have had a hard time making that decision.

The W46 is a Mitsubishi 127 cu inch. Try Marine Gear on 2nd Ave in Fort Lauderdale for best prices I have ever gotten for my W46. 2100 hrs, running great with Hurth HBW150.
$1700 for a gasket set doesn't surprise me.
Starter motor from W/beke is $900, from Masco in Charleston SC, $370.
Check bolts on rear engine mounts, seem to recall they are different lengths , and hit something if put in switched top for bottom.

This is the first time I have seen one of these engines. I'm glad to hear that you are happy with yours. Just dropped mine off at the rebuilders to be assessed. I'm hoping for under $2K.

When replacing the split gasket for the pan, it is important that the extra 1/4" at both ends not be cut off. It is necessary to carefully tuck these ends in against the oil seal retainer rings. If not THEY WILL LEAK. Don't ask how I know.
