Is my piston dead?

[jetmechG550]

Yes, the rods tend to be the first to go. They stretch and the little brass bearings wear to make a sloppy fit on the crank which will lead to premature engine failure. Don't take chances. One thing I might recommend depending on what engine that is, is that you may just want to look into a new mill altogether. By the time you bought all of what you are thinking of, in some cases it will be within in a few $'s of new mill.

Yeah thats what I was thinking. Wont be able to afford one yet because I'm getting a new guitar first, but then i will see.

MW, its a Rex P5.

 

[jetmechG550]

P/S/R are about $120, give or take a few bucks, new P5's are about $265. Go ahead and rebuild.

I've been kinda eying up an STS.. or maybe a P7-R, i saw one for $185 with 1/2 gal through it. Either way, i have a lott of time to decide.

Or i might rebuild, i can't decide.

 

[jetmechG550]

Be careful, used motors always have "less than a gallon" Why is that?

 

[Buggyracer28]

LOL true.... If I bought an STS would I be downgrading a lot performance wise? I have no clue, I've never seen one run but I hear they are nice.

Its tough to beat the performance/relaibility of a p5.

This is a small vid of me driving my 8ight with the STS D21T in it.

It currently has 7litres through it, and still has good pinch. Compression is insane. This engine has now been put on the shelf as a hot backup,since I just received my replacement engine from STS. They sent me a new D21T MK2, plus all the usable parts from the engine I sent in.

 

[Buggyracer28]

Looks pretty nice, ill keep looking around.

 

[Buggyracer28]

Well i just bought one of the last ones of these:

Hopefully that will keep me running.... Right when i was going to get the stock set, it was out of stock, so i just went for this one.

 

[jetmechG550]

Nice grab, I may have jumped on one too.

 

[Buggyracer28]

O my god! My engine is breaking in beautifully! You can really see the power already. It took awhile to get away from the piston locking, but once i hit the sweet spot and turned it over a couple times it started up first bump. I am on my 3rd tank right now and it is awesome. I can't wait to get to the track.
