As you will recall, In our last episode, I was preparing to install the
new starter in my Merc. 5.0. I did a compression test with the old starter in place, 150 all around. After sitting 2 weeks, the new starter is in; I cranked it with the plugs out (no manifolds installed yet) And it spun 3 revolutions with a *Clack* every 360°. I thought in this brief time that possibly a tooth was sheared on the flywheel ring, but after 3 revolutions the engine locked and would not turn. ****. I was thinking maybe a socket I had holding the Qjet choke open had somehow fallen into the intake manifold and wedged an intake valve open. Ok. I put a chain wrench on the balancer and found I could rotate the engine backwards, but would lock at the same point forwards. I pulled the valve covers, expecting to find an offending intake valve hung open, with slop in the rocker arm as a result. Found it, alright, but an exhaust valve, not intake. Feeling up the #4 exhaust port with my finger, I can feel the broken end of the exhaust valve stem. The valve head is loose in the combustion chamber, preventing the piston from reaching TDC. DOUBLE ****. In the 2 weeks since the compression test, the #4 exhaust valve seized in the guide, and on cranking, because the valve is at an angle with the piston, was broken off. Now I get to pull the heads...... Oh well, the engine is 18 years old, has 495 Hrs on it, and with all that down time, a seized valve is not unusual. JR JR Said: So, after I got home from July 4th cruising, I flushed the engine on the muffs. Shut it off and went to restart about 30 min later. Hydrolock. Pulled the plugs, and sure enough-clear water out of several cyls. The starter sounds like a garbage truck now also. ****. I should consider myself lucky-this is only the second set of manifolds in 18 years, 95% salt water, due to careful and thorough flushing. I found the best deal on manifold/riser kit he (free shipping) http://stores.ebay.com/Doug-Russell-Marine and cheap price on NEW Marine starter for Mercruiser 5.0 he http://stores.ebay.com/Rareelectrical and, lowest cost on exhaust boots (I'm doing the whole thing here...) http://www.go2marine.com/ No affiliations... I pulled the manifolds last night, and squirted about 30cc ATF into the cylinders and cranked it through. Because I applied anti-seize compound to the manifold and riser bolts on the last job (1996) all the bolts came right out. In fact, after loosening, they could be screwed out by fingers. I don't have any such hope for the starter bolts-they're original and I'm dreading pulling the starter tonight. JR JR Said: What a BITCH. I had to custom make a special tool to get the starter bolts loose-will post pics soon so youse manly guys that get your hands dirty can benifit from it. Absolutely no way I could get them to budge with just a wrench. I'm really amazed they came out at all. Prolly a good thing I'm doing it now; Cruis;n Rulz! is 18 years old and unlikely I could get the starter out down the road at all. It would really suck to have to pull the motor to replace a starter... Anyway, waiting for all my good deals to arrive, and to get back on the water.

Regularly my cost is $58.80 but this month they're on the sales flier for $51.50 plus shipping. You need, m'man, I'll get it headed your direction. Of course thats only one of the warehouses I'm tied in with. others may be a tad (pennies) more, or a tad (pennies) less, but still ..... What gets me is loogy's starter is bigger (not much) but is the same pricing +/- , I think because the v-4's are more popular.... |

and cheap price on NEW Marine starter for Mercruiser 5.0 he http://stores.ebay.com/Rareelectrical $89.00 PLUS shipping.. And that's a "cheap" price on a new starter? I could have gotten you exactly the same thing at my cost of $56.11 and about $12.00 freight. Ebay stores, you gotta love 'em. |

Surprised me too. No way I'm gonna just pull one head, your 3/4 way
there pulling one as two, and wouldn't want a valve to seize in the other head later(when the engine is running...). I'm just gonna yank 'em both and go through them. JR wrote: That's disappointing.

Well, you can't go wrong pulling both. Except for another $45 head gasket.
I've occasionally flat rated the job by loosening the intake bolts on the other side and taking the problem head off without removing the intake. But there's the risk of a vacuum leak on the other side. And then you end up pulling it anyway. "JR North" wrote in message .. . Surprised me too.
