Alright guys so hers the story:

Bought an 04 6spd, 180kms, was told engine was toast due to overheating.
Bought as-is - anticipating to possibly rebuild / replace engine.

Took to shop, checked compression and said there was no compression at all.. Would turn over but wouldnt start. Says it smoked really bad.


What do you guys think?
I told him about the hard starting (pull fuel pump fuse, turn over for few minutes, blah blah). Says didnt make a difference, still the same.

Just wondering if this is common?
Im not scared to rebuild but just want to make sure im doing the right steps here.. any guidance is appreciated..

thanks!

If you were told the motor was toast due to overheating then more than likely it is. If you had a compression test done period and you have no compression then your pretty much at worst case scenario. Was it done using the rotary tester? Or just a regular compression tester? Did it show any numbers at all? If not Pull the motor, Depending upon how much of the work you are doing yourself, it may just be cheaper to purchase an engine from a reputable vendor, and install it. Once the motor is toast from a significant overheat, it's almost certain the majority of parts are going to be unusable. Which would make a rebuild very expensive very quickly. You may be lucky though, it all depends on what you find once you dive into your current engine.

nah he wouldve just used a regular tester.

I bought another 04 for the motor but I think there was an issue with that (maybe low compression) one as well.. So i should be able to make 1 good one out of two duds...

Told the story to local rotary guy here in Abbotsford, but he wants 3200 for the rebuild job + $800 removal/install
(can remove myself but then think if I do that i may want to rebuild myself)


Cheapest motor Ive found is $3100 close-by (Im in Vancouver) w/ 80,00kms on it "apparently"... willing to warranty it for 6months he says..


doing a quick ebay search, rebuild kits coming up for $1200 - is that normal?! seems expensive.

just debating on what makes more sense, what u think

If you know how to rebuild a rotary then go for it. what makes a rotary rebuild difficult is that it needs alot more than just the rebuilt kit " knowledge and experience".

You are better off letting a reputable shop rebuild and install it, or get a reman engine and install it. Buying a used engine off anyone without a compression is like a suicide in my opinion. You may end up with 3rd toasted engine in your hands just my 2 cents.

If you trust that the mechanic is competent working on a rotary and you bought it blown then you only have one choice and that is to get it rebuilt. How you choose to go about rebuilding it totally depends on your skill, wallet, and level of give a *****.

Your extra parts car engine could be a dud too, the only way to know what you have that is reusable is to tear them both apart and start specing parts (if you have the proper tools to do so). But at least you have two cores, so contact a reputable builder and get after it.

Keep in mind that with only 8 major components in the engine, it is unlikely that you would actually be able to savage enough from 2 engines to build a good engine. That's really only viable if each engine only has 1 blown rotor/seal/housing combination. Even then, both the front and rear share the same center iron and same e-shaft. You pretty much need 2 acceptable engines to salvage 1 good engine.

Also, keep in mind that rebuild kits are only the small pieces. None of them include the major pieces. The major pieces would nearly all be damaged in a significant overheating, especially one big enough to render the engine with 'no compression'. Even on an engine that is just really high mileage will have housings that are chattered or flaking, irons that are scored, e-shaft bearings that are showing copper, or rotors that have seal seats worn away. A rebuild on such an engine with only the contents of a rebuild kit will net you an engine that will be dead again within 10,000 miles.

Hmm, I was just told one of the motors had no compression and the other one COULD run but it was VERY noisy like something banging around in it... Any ideas what that could be? lol. Thinkin maybe apex seal broke off and its ratling around?

Thanks for the advice so far though guys, very helpful forum

If it was higher pitched rattling, it's probably a broken seal banging around shredding stuff. If it's a banging, it is probably the rotor tips hammering into the housing due to e-shaft bearing problems. In the former, it will shred the housing, rotor, and both flanking irons of whatever chamber is affected. In the latter, it is likely to be rendering both housings, both rotors, all seals, and the e-shaft worthless. Possibly the irons too.

Wel found a local shop here in Abbotsford, BC.. $3200 for engine rebuild - 2 year warranty apparently.. Gave him the go ahead so lets see....
