As you know, Junior died. I have 3 spare engines and assorted engine parts to work with.
question 1: What's a good way to test an engine without putting it in the frame? I can have it beside the frame and connect up the electricals and throttle & choke. Is sitting on the oil pan OK for testing? Or what should I set the engine on?
question 2: I have an Autozone down the street from me. What sealer should I get for the case if I split one open to close it up?
question 3: What rubber gaskets & other buts should I get from by dealer should I put an engine back together after splitting the case? I do have 2 complete gasket kits so what's not included that should get replaced?
NOTE: I do have 2 complete gasket kits, those $80-$99 packs with all the gaskets, o-rings, crush washers, etc.
This will be my first intense engine tear-apart and put-back-together.
What I have to work with:
* Separate spare parts (in addition to the engines listed below):
** JUGS: 4 or 5 and the honing tool
** PISTONS: a pair from the same jugs plus a few others
** HEADS: 2 good spare heads
* ENGINES:
** 1989 with supposedly bad compression. Head looks good. Can put on good jugs and the pistons that came with it. Bottom seems good.
** 1989 engine with same issue reported and bad pin for timing rotor, so may part out this engine. May use transmission if necessary
** 2006 engine that was said to have a timing chain guide disintegrate. Reported to run OK but oil light comes on after 20 minutes. Returns to normal if you wait and start up again. Will remove bottom oil pan and take a look. Could be oil pressure relief thingy which requires splitting open the case.
** Junior's engine. Not sure of real problem but head looks good. Will need to remove jugs to see if pistons are good. Problem either piston or transmission.
So this weekend I want to get something done - even if a temporary engine into Junior.
Photos are in the project area and I will update that after this weekends work. So I would like to try something.
Thinking of the 2006 engine to see what it does with Junior's carbs and old timing rotor and pickup. That would be easiest solution if it works. (It does turn over with a battery to the starter motor.) Then fix up spare engine in the next couple weeks however necessary.
Wow! No suggestions. No advice. :sad: :cry:
I'll buy a big a hammer. Do this :technical: then buy a new engine.
Since you asked nicely... :laugh:
1. Never done it. You could hook the starter to a battery and check compression. I wouldn't run it without exhaust.
2. I use Toyota black FIPG and Yamaha Yamabond which aren't going to be available at Autozone. I assume they carry Permatex products, just shot gunning it I would use the red high temp or the black silicone.
3. Don't know what's in the gasket kits you speak of but I like to replace the 4 o-rings that pressurize the top end.
I would do Junior's known good top end on the '89 bottom end with low compression. Seems like the path of least resistance to me.

Question 1: I'd get an old wooden skid or build some sort of scrap wooden frame out of 2x4s to test. This way, you are not damaging cooling fins and you have a mostly unobstructed view of the engine while testing. Agree with exhaust...you need it or else it will be lean and that causes heat issues.
Question 2: High temperature sealant (quality one) would be a start. Maybe ask the service and/or parts people at Aurora Suzuki what they recommend? After all, don't they call you sometimes?
Question 3: Agree with Baltimore on this one. Not sure what gaskets you are referring to.
Not sure if I have to:
1. Split the case
2. Trash the bottom end and reuse the top - scottychop and baltimore think this is best. I tend to agree as the bottom end is full of shredded metal dust.
3. Can fix without splitting the case.
Thanks for the advice. I appreciate it.
