rebuild

[MoonRaker]

Ok, ive gotten my final quotes for parts and machining.
Keep note that im building a 200,000 mile engine so not all figures apply.
Rebuild kit from promar engines, includes pistons and gaskets and oil pump $850.00

All in house machining from Promar, 0.010 over stock and including crank $500.00

nickel plating and diamond honning $800.00

Total cost = $2100.00

This is great, better then a $3200 shortblock. Im betting it can handle an extra 60 HP load and not have an affect on milage out come. The nickel plating isnt a must but I do it to all of my motors to decrees were and tear, and it also decreases friction and heat. Here are the sights to the vendors.

Any more seggestions would be cool.

Well, im on my last few steps of my rebuild. Its taken longer then I planned because it was set on the back burner for some time but ive been left no choice. I totaled my other vehical and getting a new one isnt a good option at this time. Ive gotten all of the machining finished and built the long block in the last 3 days. My findings were 1, cracked ring and 2, oil rings had no spring and were kinda stuck. It looks like a manufactureing defect with the oil rings to me to be the cause. The oil ring groove in the pistons were to tightly clearenced causing many engine issues ive seen with other owners. Id recomend everyone getting a compresion test and leakdown test if you have any bad engine symtoms such as oil burning before your warrenty runs out.

A leak down test would be expensive, since you would have to remove the cams. shawn

Just bar the motor over and do 1 hole at a time. A motor job costs 7,000 or more for the VX by a dealer. Im sure a leakdown test dosnt cost that much.

As it sits ive spent $1250 sofar on parts and machining. Ive done everything except the nicol coating and since the motor has steel sleeves and dosnt require it but that would have been optimal. I need to get some bearings for a pully or 2, probly another 20 bucks.

To properly do a leakdown test you need to remove the cams.If you were to cheat and not remove the cams you would have to try to hold the crank in one spot so it does not turn.. And this test would not tell you if you had a stuck oil ring anyway. It would tell you if you had a valve issue, or a compression ring issue. So this test would not even tell you if you had a stuck oil ring.You work in a motor shop?? shawn

Yeh, were the best in the US on rotarys. Yes, 1 of the compression rings were cracked. This is the 2nd motor that ive herd of that had the oil rings sticking with bad springs and I called it as the problem before I stripped the motor down. No I didnt do any leakdown test because it already showed signs of potential total failer so what was the point.

Were you able to take as many pictures as you'd hoped, since you were in a hurry?
