That engine would scare the be-jezus outta me..


I'm wondering what I'm getting into. I think I'll pull the other engine apart and see why it's smoking. It may be better to use that one. My whole gt life is a mess lol

Just investigate what you have there and replace the rod with the correct one..  Check the cam spec's to what the Manual states for your engine in the Manual (you D/L & save it to your H/D yet?)  and if they are correct you will be fine!  Toss those 'Grenade Gears' into the scrap pile!!!

Who would put an engine together without cleaning anything? 

 

Some people do some stupid things either through ignorance or... stupidity.

The difference between genius and stupidity is that only genius has limits. There is no limits to stupidity as our government likes to demonstrate.

I'd completely disassemble and clean that engine. Then I'd carefully inspect every part and wear surface with a magnefying glass and my mics. The cam would get the indicater treatment. Just follow the manual. Don't buy any parts until the inspection and any machining is complete. Good Luck, Rick

Is everyone saying the gear are not needed in the engine?? I don't know myself.  I would clean it up real good and reuse what you can. I think in the end you will be fine just getting in there and getting your feet wet.

 

That isn't even the work of a decent shade tree mechanic, but who knows what a PO would do to make a sale.  Good luck with the end product.

 

Like you had said you may need our help- well so far it looks you have a good following of helpful men.

I recommend using the service manual that was listed. It's very good. I'm suspicious of the gasket shim. Was the deck previously milled, or was the man trying to lower the compression? I would take the engine apart and check everything. Mic everything.

It has two gaskets and a spacer. Supposedly the rod is to short per previous owner. All I know for sure is that there is no compression. Thanks for the manual. I downloaded it some time ago. I roughly thumbed through it tonight.

if it took 2 gaskets and a spacer the rod is either too LONG or the wrong piston is in there. Different engines may take the same diameter of piston but the wristpin hole location may be different  which will make it hit TDC at a different spot

That piston should stop directly even with top of the block before it starts back down as the crank rotates. There should be 1 head gasket between the block and head, that's IT.

This has the wrong piston and/or rod. The piston stops above the head but about even with the spacer. This engine is on hold until I get the other one apart. I'll post an update when I get working on it.

Can you imagine the work to machine that spacer? Woulda' been easier to change the rod.

I looked at it closer tonight. It actually looks decent but not professional grade.

The plate and piston numbers. By looking at the gaskets I would guess one old and one new.

Everything engine wise so far has been from engine M. Everything in this post is engine S. Engine S smokes to the tune of a quart a hour but I drove it in the shop when I tore it down for these pics. Pistons look the same rod from engine M appears longer.

The pics from engine S

Well, that kinda solves the mystery, doesn't it? What are the numbers of the two rods? ( if any)

Now that I see the picture, do you suppose he sawed the top off of another block?

Definitely a difference in the rods,even the oil dipper on the end of the rod appears to be longer.

 

Just thinking out loud here maybe the longer rod and spacer were an ill advised attempt at building a long stroke k-series? Or am I giving whoever put it together to much credit in the IQ department?
