Please help. Detonation problems
 

Hi!
I am having troubles with my front rotor in my RX7 93 13b-REW engine.
It won’t ignite!
The story...
I just bought a modified RX7 with all the things I can imagine.
It was mapped on 0.8 turbo pressure but when I talked to the guy I bought it from I misunderstood, he told me that I could bring it up to 1.5 on the turbo but I didn’t get it had to be mapped for it before I pushed it …
So after I went out and tried it on 1.5 pressure it didn’t go that great.. Oil in the engine room...
First the fill oil line was loose, then I went out once more (with 0.8 pressure on the turbo), after that the oil-stick popped up and was leaking oil.
Tried once more and the oil-sump seal went… haven’t tried it again.

The problem…
Now the front rotor isn’t igniting.
I tested the compression and got 6.7 kg/cm2 when I crank the engine on the starter, and got new sparkplugs.
Still NO detonation… got sparks and fuel tough.

It’s my first rotor engine and I would like to get some advice on where to look and what to look for.

It is a high tuned engine so it should manage higher turbo pressure, but as it was mapped for 0.8 and I pushed it to 1.5 something happened
One more question..
There is a oil “dump” line running back to the exhaust and is spitting out oil.
Shouldn’t the oil be lead back to the engine?
What is the lines purpose?

Thanks for any suggestion!
Regards
Mike Sweden

take a picture of this oil line going to the exhaust please.

Okay.. will do that.
How can I edit the post I put out by the way?... "Detonation" is not a very correct phrase to have in the headline :)

ya there's a edit button at the bottom of ur posts

ya detonation is BAD... I think u mean to say Combustion or ignition :)

Yes.. I mean combustion ;)
I do not have any edit button, I just have that when I just posted the thread, then it goes away... (?????)

Mike,
What You've got is a broken Frt. Side Housing, besides a 1/2 blown engine.
The OIL is not coming fron the Turbo feed line, it is coming out right below the banjo nut that the Turbo feed line originates from.
That why there IS oil every where.
It's not a lose Oil line, cause it wasn't pouring oil out when You bought the car.
This is "the clasic overboosted" 3rd gen, although most steel plates crack at the rear plate instead.
Sorry for the bad news, but You'll find when You tear the PS., AC., & support bracket off for a better inspection, the front steel plate is cracked right bellow the oil line.
As to the front Rotor not lighting off, that because You've got broken seals in there, and possible more damage to the Rotor & Housing.
You may have also damaged the primary Turbo, if an Apex got spit out.
This is the WORST possible senario that I've just descrived, but experiance tell me that MOST of this HAS taken place.
Hope You have better luck, & I'm incorrect !
Best Regards.
