I think the rings are interchangable but the E model pistons are higher compression. They will fit the earlier engines just fine if you use a pair of them. Clearance specs are the same.

Also are the specs for the 500e the same as the tx500 in terms of cleareances?

The magnet goes in the sump. A digital caliper is not accurate enough to measure your pistons and cylinder bore. Take your parts to a competent shop that has proper micrometers and bore measuring tools.  It has to be done precisely or your results will not be what you want.

I have a small circular piece in the oil pump that seems like it is just there? Did it fall out of somewhere or is it just a magnet to collect metal in the oil?

Valves all cleaned, lapping tomorrow.


....caliper comes in tomorrow to measure pistons, etc

One you take it down have the cylinder bore and piston measured. If on its original bore, still in tolerence with regard to skirt clearance and undamaged then a light hone and new standard rings will work. If it is above standard bore size then spend the money and get it bored for the next oversize with new pistons.

I will take it apart I guess :(

If rings are shot would 0.25 rings over work without a rebore do you know?

The jets are not going to help. If you had the tools a leak down test would point conclusively to rings or valves as the cause of the low compression. Im thinking valves as the compression did not jump up a lot. Either way the top end needs to come off the engine to fix it. Sorry.

So I rechecked compression and it was 115, about 118-120 with oil in the cylinder. Is that enough to signify the rings are bad?

I had checked the compression before I redid the valve gap so im assuming that is why it jumped up? Still cant get her to run though, the new jets should be here later this week and hoping they help
