Title: Turbo\'s blown??
Post by: MarxMcrae on February 16, 2007, 01:00:10 PM
Right then yesterday I was driving home from work an wasn\'t exactly going slow. That not to say i was redlining the engine, but. I changed from 3rd to 4th and was accelerating when the engine suddenly lost power and started to make a sort of grinding noise (thats the best was I can describe it!) it was also very load! Anyway I immediatly pulled up in a layby to have a look. As soon as I pulled up the engine cut out, I tried starting it again which it did but cut out again when i took my foot aff the accelerator.
The oil pressure seems fine, and the water temp seems fine so im pretty sure its not the engine itself. Theres no blue smoke coming from the exhaust, but its as though the turbo\'s arent working as the boost guage wont go past 0, but still idles at -5.
Im really hoping that this is just part of the exhaust that has broken loose somewhere.
Anyone with any advice or ideas would be greatly appreciated!

Cheers Marcus

At first, it does sound like you have chipped a seal in the engine. Is your boost gauge fluctuating when you switch the car on? And by how much?

Also, what ECU were you running.

Check to see the map sensor is still intact.

However, from what you say about giving car WOT and down shifting etc. If it was on stock ECU then I would say engine.

Anyway, do check the boost gauge etc and map sensor and report back.

All th best.

Also, how did you get the car home. Is it driving? Does the car seem shaking when you start the car.

I actually drove the car home as it was only about 2 miles.
Im running a standard ecu on a 93 import.
I\'ll go and check the boost guage reading now.

Right then I\'ve just checked the boost guage and yes it is fluctuating.

A fluttering boost gauge on idle is not a good indication mate :-/

Find some one near with a compression tester of some kind would be the easiest course of action, that will tell you if the motor is intact or not before you start pullling stuff off for the sake of it.

Sounds similar to what happened to mine - except I had a loud pop and the engine sounded like a lawn mower.

Not sounding good - but best of luck mate!

Sorry to hear that mate. It is always the dreaded with these cars in my case anyway. :(

Hopefully you havent caused too much damage to the engine.

Keep us updated.

First thing you want to do is join MRC as a full member - you can get discounts on everything including rebuilds (from Hayward I think).  It will pay for its self over and over again.

Every little helps!

Out of interest, how many miles had you done? was it a rebuild?
Title: Turbo\'s blown??
Post by: MarxMcrae on February 16, 2007, 06:27:08 PM
It was a doner engine from a breaker as my original engine had blown due to a water seal failure. Engine had a rebuild approx 12000 miles before i bought it, and it has since done approx another 30000miles so wont be able to get it done through warrenty unfortunatly.
In regards to becoming a full member, i\'ve always considered it as i\'ve been on here for years but never seen any benefit to it.

 Now thats a slap in the face for the \'Free\' help you seem to have gotten here over the years! Wonder how many thousands you have saved from the \'FREE\' advise you found on here....
 Example now, why didn\'t you just go to a dealer/mechanic and let him charge you a couple hundred for test or whatever to tell what we have told you today for free!
 
 It\'s ok mate, us \'paying members\' will continue to pay for the upkeep of this site so other gratefull people will appreciate the friendly advise we offer and put together for the benifit of all.
 
 I think your future advise here may now be limited.....  :Yawn

I dont mean to sound ungrateful to the forum, but if you look at it from my point of view, i\'ve been using the site since 2004 and only only posted 90 odd times so £25 each year for 3 years (£75) would not be worth my while

I can\'t see that the post count is relevant, surely it is more a case of how much help and information has been received from reading and gaining benefit from the vast array of information that is provided for FREE.

I\'ve said this quite a few times now, I bought an RX7 new it was unusual and that I would need to seek advice.

I don\'t like taking anything for nothing so I joined.

Felt much better about asking questions, but that\'s just me.
