v6shep Posted May 23, 2016 Share Posted May 23, 2016 So, had a few crappy months with the supra, when I say a few, I mean it's probably done 60 miles in 14 months. First started as a gearbox problem which (fingers crossed has been resolved). Which then led to very poor idling, then bad misfiring, until eventually not wanting to start at all. Read my error codes, got advice from a few helpful as always members of this forum. Replaced a few bits here and there, which to be honest, where most likely the original parts from 23 years ago so where probably due to be changed anyway. But, after doing these odd bits and bobs, still nothing, until last night! The car was towed over to a garage I know and we Both got cracking on with it. Fired up a few times, sometimes running rough, sometimes sounding sweet, either way,at 2k rpm, instant cut out. Tried one more time, it fired up! A little rough, but running, my mate ran over to his tool chest to grab a spanner to loosen the distributor to adjust the timing, just as he turned to come back over, all of a sudden, smoke starts to appear from under the hood... He ran over, I switched supra off, both get straight under the hood. Now picture, those old-school fellas who enjoy a bit of the old "glass blowing", molten glass, glowing an extreme orange, and slowly expanding... Then imagine that as a CAT on my car...

mwilkinson Posted May 23, 2016 Share Posted May 23, 2016 So the cat had perished and collapsed on the inside and this restriction was probably the issue with the car? Has it done any more damage? Link to comment Share on other sites More sharing options...
v6shep Posted May 23, 2016 Author Share Posted May 23, 2016 I'd say after all the drama, even though I'm the least mechanically minded person I know, that yes, it HAS to be the cat that's caused me so much stress and anger. Obviously, the car hasn't ran at all long enough for me or anyone else to draw it down to the glowing molten first cat. The only other visible damage we could see, as 4am was closing in and hours of endless stress, was a large oil patch and a pipe (not sure what pipe as not looked) was bent up in the way of the fan Link to comment Share on other sites More sharing options...
v6shep Posted May 23, 2016 Author Share Posted May 23, 2016 This is obviously just a guess, but the pipe in question is at the front lower area and I think is/should be connected beneath the pulleys Link to comment Share on other sites More sharing options...
Scooter Posted May 23, 2016 Share Posted May 23, 2016 If it's the one that should be attached underneath the front of the sump, that is the power steering. There is not a lot of fluid in the system so if there is a patch on the floor then the reservoir should be down/nearly empty Link to comment Share on other sites More sharing options...
v6shep Posted May 23, 2016 Author Share Posted May 23, 2016 (edited) Phew, I was hoping it would be that. Looks like I'll be hunting for power steering pipes now :-( There was a patch for sure! But it didn't seem big enough for it to be anything else really, it spewed onto the floor, then just dripped, not like an oil slick if had been anything else. It's bent right up between the fan blades Edited May 23, 2016 by v6shep (see edit history) Link to comment Share on other sites More sharing options...
Scooter Posted May 23, 2016 Share Posted May 23, 2016 Pictures might help that seems odd? Link to comment Share on other sites More sharing options...
v6shep Posted May 23, 2016 Author Share Posted May 23, 2016 I'll get some tonight. Obviously if cat has collapsed, the pressure build up is mental, and I agree it could be power steering pipe, but don't get why that would have been affected Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 23, 2016 Share Posted May 23, 2016 A blocked cat will have no effect whatsoever on the PAS system. I suspect the cat has melted due to either very weak mixture or more likely very retarded ignition timing or wrong cam timing. Metal substrate cats rarely collapse internally due to old age, in fact i have never, ever seen a Supra cat mechanically fail internally. Link to comment Share on other sites More sharing options...
Swampy442 Posted May 23, 2016 Share Posted May 23, 2016 both get straight under the hood. Whilst wearing galoshes? Did you fill it full of gas too? Link to comment Share on other sites More sharing options...
ripped_fear Posted May 23, 2016 Share Posted May 23, 2016 My mates na last year was having running issues and both cats had collapsed too. Just take the exhaust of and fire her up and I guess if she runs OK then you know that is your only issue Link to comment Share on other sites More sharing options...

I didn't think a possible 23 year old cat would be indestructible Link to comment Share on other sites More sharing options...
