Ok,

I dynoed my car today, my cars HP was way down from where it was previously, but on the last run when he let off the car just went nuts at IDLE. It backfired and then the idle was a bit uncontrollable.

Since then when I start the car hot I have no problems starting, but my vaccuum on my power FC used to be about 480, now it is around 320 or so. I can drive the car to the redline and I dont notice major loss of power and the car just feels like its hesitating a little. The only noticable issue is when the car is at IDLE.

Anyone have any idea? My first thought was I blew an apex seal, but there is no smoke, coolant loss, etc. Also, driving the car to redline is not a problem. Also, I can get full boost with my turbo.

Any ideas?

Thanks.

The other thing I should mention, the idle is steady around 860 RPM, but the car shakes a little. You can see the manifold shake, and you can feel it when you are at IDLE in the car.

Im taking my car in to my mechanic on tuesday, but any ideas will help. Thanks.

sorry to hear, seems like the dyno day today caused a lot of problems for both of us

Comp test man. Cracked apex seals can do just that.

Im sure its my engine, I went to the store and my car degraded, the car was from 100-200 on vaccuum and I notice when I shift that white smoke came from the back of the car. My car could not even make it up a hill on the way home.

oh well. Anyone want to buy a FD?

Damn..... that REALLY sucks

ZeroBanger

It will not even start now. OH well. I put it for sale.

rynberg

**** David, that really sucks. I feel bad for pressuring you to dyno now.....

Well, let's see what Rick says on Tuesday, but it doesn't sound real good.

Let me know, man.

Its been fun, but the game is over.

rynberg

Damn man, how are you going to replace the FD? 350Z or RX-8?

I guess it's pretty definite it's a blown engine but I would wait until Tuesday to know for sure.

Man, this really sucks.

Already given up?

Resource

I'll buy it for 4K?

ZeroBanger

I dont know, my mind is a mess right now. I put so much of my heart into this car.

S2000, miata, RX-8, 350PIG, Civic.

I still want to keep it.

r0t0r-rooter

WAIT!!!! All is not lost (yet).
Get in touch with DCrosby.... he was on the SoCal7 cruise this last weekend. Work something out with him

It sucks to hear things like this..

ZeroBanger

I'll punch you for 4K.

Deal? Hell I'll do it for free

Resource

3200 and you got a deal.

ZeroBanger

work out what with him? thanks.

Man, that sucks, but maybe you just lost the leading coil, the white smoke *could* be excess fuel not being burnt. Do a spark check and compression test before writing it off.

Good luck,
Frank

Loss of vacuum sounds like the compression is already gone, and unburnt fuel is black smoke.

Sorry, but this engine sounds like it's in need of a re-build.

Sorry to hear about your engine. Just get a new one and you are back on the road. My friend Greg was at the dyno day. He had a 94 MB touring with a few bolt ons and a stock ECU. He left before you dyno'd. He didn't know you had a problem.

Good luck with the repair. You can't sell it because: The 7 can't lose!!!

scratchjunkie

i agree the 7 cant lose!

Don't give up. You've contributed a lot to this board and this car, and it would be a shame to see it end.

A new engine and she'll be good as new!

ZeroBanger

Thanks for the support, i really appreciate it. Im taking my car in the shop today. It seems to start in the morning and if I keep the revs above 1000 its ok.

I'll let you all know

SPOautos

Just get a reman from Ray at Malloy Mazda and do the work youself. It'll end up costing about $2500 total but your probably going to loose a lot more than that by selling it blown

i'm sorry to hear it man, I've been there and know just how you feel.....and it sucks

ZeroBanger

yea, I'll just attach a chain to the roof of my car port, attach it to my engineblock, losen all the nuts and try to lower my driveway


Really, its gonna cost me about $5,000 to $5,500 to get this done. I almost killed my freakin engine a year ago after removing my stock air box (you dont want to know). So im not touchin' any part of this.
