How long are you attempting to start each time? Badly fouled plugs could be possible as well, I guess.

Thanks for the reply brother. I actually hooked the car up with jumpers to my Honda and did the pedal to the floor de-flood procedure after unplugging the air pump, about ten de-flood cranks and all of a sudden boom, she fired up and we had a hell of a smoke show. Took her out and beat the block hard and I have to say, he was having some issues with power loss through third gear and up and it's all back to full power. The plugs were definitely flooded out real bad but shes back running. Now only if we could fix this no hot start issue I'd be happier. The car for sure needs a new motor but I'm trying to buy him a couple more months while he saves up for a new engine. I'm thinking LKQ is probably the best place to find a reasonable motor to swap in? Thanks again any details help. Especially with this d*** hot start problem it's such a pain in the rear.

It's a headache man but it's my boss's sons first car and he loves the thing. Just trying to buy some time here. Anyway you know to temp fix or work around this hot start problem?

I would really like to give the a-hole who sold him a car with bad seals a nice smack in the mouth.

Well, I would not assume anything. But before he spends more money on doing a proper tune up and troubleshooting other things, spending $100-150 on a dealer compression test would be the best money spent. If the engine is below spec then he should just cut his losses and move on. If the engine has good compression (hot hard starts can be caused by other things) then he needs to figure out the problem.

But seafoam is a huge waste of time, it accomplishes nothing and typically causes issues.

When they first suspected issues they did have a compression test done. The results weren't great but not horrible either from what was relayed to me. The thing is when I was looking over the motor one of the boots wasn't fully fitted over the plug and then I noticed it wasnt even screwed in all the way so the tech whom did the tune of prior to this obviously doesn't belong working on cars. So I'm curious if that was part of the cause to the poor results from the test.

Also the car was having so many minor issues and had such a lack of maintenence history that I figured by this point the seafoam was worth a shot and to my surprise there was pretty drastic positive results from running it through. Only used about 4oz per port. Also ran a small can of Restore through the oil and the compression and performance seems to be up. I've used it on plenty 4 bangers with good results so it was worth a shot. So far the rough idle is gone, car hasn't been stalling out, no more loss of power between 3-6 gear. Between the two I feel like it's given it a little longer life span not that I'm crazy about dumping tons of shit in the car but it was all worth a shot before having to pay for a whole new motor. I'm going to see if the dealer will run the compression test again considering they left a God damn plug almost out.

Restorer? Come on man that shit is snake oil and will have no effect on compression in a rotary.

If the compression was passing then the hot start issue is something else and the car needs to be properly troubleshot instead of just guessing. The loose plug and boot could have been from when they did the compression test. Do they have the printed results of the compression test? Was it done by a dealer using a rotary engine tester?

He got a print out from mazda of some sort , they claim they did it. Not sure how detailed it is but I will ask to see if I can get a copy. I feel like it should go back for a proper one considering the loose plug though. What does a beefier starter usually run? I'm not a big rotary guy here if you haven't noticed there just not really my thing but I'm trying to lend a hand. I'm guessing new ignition coils wouldn't be a bad idea as well, what's it like getting those out to replace?

If you want to help start troubleshooting. Otherwise just tell them to take to a qualified mechanic, it doesn't have to a rotary specific mechanic, a good technician should be able to get it sorted.

Appreciate your input bro, I'll check that out. I see its labeled RX7, does it apply to all the same things on the 8?

9krpmrx8 03-14-2016 11:40 AM

It's from the RX-8 factory service manual. The site just caters to 7's and 8's.

It's just the path to the file, it is the RX-8 manual.

Good stuff. Thanks again

Seafoam spray into air intake boot?
 
Bought some seafoam spray and the official video from seafoam says to spray it into the air intake boot while idling at 1000 rpm above its normal idle rpm. Would his work ok for the rx8? A lot of rx8 videos have you unhooking various plugs and what not but the other way seems way easier

Steve Dallas 04-16-2017 09:31 AM

Every method of seafoaming this engine is ineffective, so spraying it into the intake should maintain the status quo.

zaxter530 04-16-2017 04:22 PM

How is it ineffective?

By not doing anything.

zaxter530 04-18-2017 11:45 PM

Thanks for explaining that to me
