Title: Not starting.
Post by: Nicolai on December 11, 2007, 02:32:52 PM
Hi Guys/Girls,
 
Im planning to buy a broken Rx7,
The rex wont start, the owner says because of the carbon buildup. Stands still because of other projects.
It can be tow started, and runs strong he says. (turbo\'s also checked and are ok)
Also he says he did a compression test and 1 rotor had a 10% loss.
 
I was wondering if you could help me,
Does is sound common in anyway?
59k mark is the milage. (does it need a rebuilt straight away or can it be something else?)
 
 
Hope you can help me,
 
Thanks,
 
Cheers,
 
Nick

treat it as a blown engine...you cant buy a car that will only start by tow-starting as anything other than dead

Yes offcourse, buying it the cheap ;)
 
Thought of that myself(it will be a project), but is there an option that it can be something else?
When I make my trip (form abroad) he assures me that he can let me hear it run, it is drivable onces tow started.
 
Thanks for your time :)
 
Cheers

If it turns on the starter but doesn\'t fire it could be low on compression as the tow start will run the motor much quicker than the starter can and get a higher compression to get it started.

That\'d be my first thoughts anyway.

i think you are kidding urself if you think that it might be any sort of easy fix. It does sound like low compression as Mark said above, tow starting will turn the engine over much faster and give higher starting compression.
How cheap is cheap?

Yep low compression = time for a rebuild of the engine. £1500 if you can do it yourself, or else £2500 - £3000 for a company to do it.

For 2k I\'d expect a very decent car with a duff engine, so make sure that you go over it very carefully (assuming it\'s an FD - 250-500 quid if it\'s an FC...). I\'d actually try to haggle him down a bit further, but that\'s just me.

He wont go further down.

2k is more than the going rate at the moment for a car with a blown lump....i think I know the car you are talking about.....PM en route.
