Sad to post this.  

I was on the way to a veterans day parade and my TC stopped running.   Didn't know why except its always either: spark, fuel or air!   After towing it to the shop she basically needs a short block.  Cam gear sheared off teeth, and fried the distributor.  I think that means something more significant like an oil sending unit or pump.  That's what the mechanic says.....

Anyway, it's an auto trans, which was rebuilt once and shifts fine.  

1) Has all of the bells and whistles except for leather seating  and the EQ.  Has moon roof.
2) New u-joints with a balanced drive shaft.
3) Turbo is fine, no issues and has a new turbo gasket.  Spools up just fine.
4) Has been repainted at least the top panels, but I see no rust anywhere.  
5) Snowflakes are nice and clean.
6) Front of the engine has been rebuilt: Tensioner, belt water pump when the head gasket and valve cover gasket was replaced about 4 months ago.
7) New Monroe shocks all around
8) 153k miles


     
   
   
   
   
   
   
   

I've had her about 2 years and have given her all the necessary maintenance as needed.

I live North of Raleigh, NC.  I'm asking $3500 (that's what I have into it).  Feel free to PM any questions.

Super nice car from California.  I'm not a mechanic so all you gear heads out there who are, this is a really nice example with no rust.  Unfortunately for me, it's time for someone else to be with her....

She's ready for that swap you've been waiting to do.  Smile

It seems that your aux shaft and distributor gear have given up the ghost. Chances are the oil pump is fine. If you pull the distributor you will be able to see the aux shaft gear and also be able to rotate the oil pump drive to see if that moves freely. Depending on how the two gears look (aux shaft and distributor) you will be able to get an idea of how much debris may be in the oil pan. Correct way to repair is removing the oil pan to clean out any debris, however you may be able to fish out a lot of the pieces with a magnet on a flexible shaft (like one of the magnetic pickup tools) that will fit through the oil drain plug. Using a larger magnet along the outside bottom of the pan you may be able to drag some pieces towards the drain pug are. Perhaps a small scope can be used to take a peek inside.

If you can get the debris out, then swapping the aux shaft and distributor gear should get you back running.

Unfortunately, chances are you may still have debris that will lock up the oil pump and strip oy the aux shaft and distributor gear again ;(

I appreciate your response.  My mechanic said several teeth on both have sheared off, so...I'm not confident that what you suggest would work for any length of time.  I just think the old girl needs a rebuild.

If I don't sell it by spring, I'll see what I can do to get her back running again.  She's such a nice car as you can tell by the pics.   

If money wasn't an issue, I'd  love to put in a coyote crate motor and a super charger with a 5 speed (dreaming (Motor City Muscle are you listening? )), but would settle for a rebuild and a M/T swap.  If I rebuilt it, then I'd go with with everything that people do to their M/T cars: new fuel pump, injectors, ranger cam (or something), new turbo and exhaust.  New ECU for tuning.  I'd love to be at 300 HP or better.

Thanks.

That looks like a nice car overall. If I had the extra cash I'd buy it but my car is sucking up my spare change right now. If you decide you want to rebuild the engine let me know, I'm not far from you.
