    Houston….. We’ve had a problem…..

    and a quickie of what I believe to be the root cause of the problem.... the wrong spark plugs..... no chance the plug on the left wasnt overheating...... with that many threads in the cylinder, I am lucky to have gotten all six out

    Houston….. We’ve had a problem…..

    ok, so the healing starts today..... new valves, intake and exhaust came, along with some other parts.... Machine shops are backlogged for months, so these are just getting lapped in. Not the "best" way, but has worked for decades in many engines in the past. Will work "good enough" for this one...

    Houston….. We’ve had a problem…..

    That’s what the general thought is. Brought the valve and plug into work and showed our bus mechanic, and he thinks the same. Wrong plug, torched electrode stuck in valve, and that’s all she wrote…. It’s a standard bore and judging by many clues, it’s never been opened before. This one will live...

    Houston….. We’ve had a problem…..

    that is the current plan... get the heads done, service everything, and get it wet.....

    data tag location

    yep, looks like the same inside as engines Ive been doing since I was a kid.... as you say, nothing special, and definitely not at the top of the heap for performance. If I had my druthers, I would completely redo the motor, (or v-8 swap it) but that isnt in the cards for this year. I want to...

    data tag location

    yep. even though it has the plastic "Vortec" valve covers on it, it has a set of 181 heads, which are distinctly non-vortec...... looks like a pair of 3/4 scale smallblock emissions heads.... pistons as well with the small dish and 4 valve reliefs....

    Houston….. We’ve had a problem…..

    at this point, its only another head gasket away..... but I dont expect any surprises on that side.

    Houston….. We’ve had a problem…..

    Offending valve is out. Seat looks OK, so a quickie valve job, and a set of valves should have me reassembling this monstrosity..... Even if the 4.3 is 3/4 of a small block, the head sure didnt weigh any less...... ahhh good old cast iron...

    data tag location

    Figures... doesnt do me a damn bit of good now for ID purposes though..... At least for 95, there was only one 4.3 combo listed, so it should still be easy to find the correct parts....

    Houston….. We’ve had a problem…..

    yes, it does to me as well. but with a known bad fuel pump, who knows how they got it "home".... I figure I was gonna go through the carb anyway, so I can tune it to my liking once I get the motor back together.

    Houston….. We’ve had a problem…..

    well, in the interests of science, I pulled the valve cover this morning, figuring if it was a tuliped valve, that it would be sitting proud of the others, and the rocker tight while on base circle on the cam.... no such luck... so I pulled the head... and yeah, there is a problem... #4 exhaust...

    Houston….. We’ve had a problem…..

    New to me 1995 Four Winns 170, 4.3 motor… Looks like I will be tearing into the engine sooner rather than later…. #4 plug shows malice in the combustion palace……zero compression. Its neighbor shows 150 in #2. #6 also shows 150…. So it’s NOT a head gasket…. Maybe I get lucky and it just...

    data tag location

    having issues finding the data tag on my 1995 4.3 engine. I found the one on the outdrive, but cannot for the life of me find the one for the engine. Does anyone here know where they are hidden?

    It followed me home honey, can I keep it.... PLEASE.. PLEASE

    I read the link. that page pertains to the earlier OMC Cobras (pre-1995) with the flat top gearcase. Still a LOT of good information there. Mine is the humpbacked version (like the King Cobra, but not impossible to find parts for) which is the "same" as a Volvo SX of the same year. Personally, I...

    It followed me home honey, can I keep it.... PLEASE.. PLEASE

    checked the shift cable by disconnecting.... The shifter on the drive works beautifully.... the cable however is stiff as hell.... so its wrecked. Time to pull that out and see how long I need one.... And So It Begins..... :D I will say this..... Volvo have a GREAT system for checking the...

    It followed me home honey, can I keep it.... PLEASE.. PLEASE

    put the battery from the other boat in this morning, and checked the trim.... Drive goes up and down with no issues, and no apparent leaks/leakdown, so that is a winner in my book. I still dont trust the cylinders to keep the drive up when going down the road, so a set of trailering clips is on...

    It followed me home honey, can I keep it.... PLEASE.. PLEASE

    not yet.... I have a full set of manuals on the way for the boat, but they wont be here until late next week. Until then, its "fake it til you make it".... but the known issues are pretty common.... like a starter that just "clicks" and a fuel pump that has conked out (that will be a week to get...
