IF I KNEW IT BE FIXED!!!!! Whatever it is I cant find the problem and I am so done. Two full days diagnosing and working on it is more than enough for me to want to shoot it

Doug. It was undrivable and just finished putting it back together a few weeks ago....Now I can drive it but......

Ill let you know how it turns out and maybe make a visit. BTW I finally got to send that thing out to you today. Sorry for the EXTREMELY LONG delay.

No problem, hopefully Chris will figure it out.

what were the symptoms? I like knowing about these things for future referance...so you just rebuilt your engine?

To make a long story short I blew head gaskets last year..And did them in the rain so I could make it to Carlisle.

Car ran fine but I always smelt antifreeze...Turned out I cracked a head..Well car started to lose power then started to break up a bit but it would get worse then better till it just got bad.

So I pulled the heads...Saw the crack got new heads....

Put it all back together with some upgrades...same issues

Seems to be ignition related but checked everything and cant find the issue.

When datalogging when the car goes under heavy load it seems to pull all timing.

Turned knock sensor off in tune..Same issue.

SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO I:M DONE!!!!!

(this is the extrememly short version)

Hesitiation, stalling, no power, hard starts, loses all timing under load and runs better with the cam sensor unplugged. After spending hours and hours changing parts and testing things, Its been sent to a local professional who loves a challenge.
This morning after reading the extensive list of what was changed and what its doing, he said had a idea of his plan of attack and this afternoon Ill see what he checked out and what he plans next.
Hopefully its something stupid and cheap.

BTW, I dont own a SC and have no plans of getting one, but since I spend so much time under the hood of Damons I feel that I do own one!!!

So before you blew head gaskets it ran fine? gotta be something you did (no offense)...its rare that things go bad when a car is not being driven...

Hope it gets figured out! keep us posted

It ran like crap before we pulled the heads off. It just so happen that he noticed a cracked head so since it was apart, he upgraded.

I have seen this happen before. Someone cuts the head surface to clean it up for the head gasket job and then the car runs for crap-0-la.... By cutting the heads you have made the push rods too long and you are hanging open some or all of your valves. This gives you the exact same issues you are talking about here... Not knowing everything you have in your engine but reading what little you are giving us would lead me to see if those valves are closing all the way or are you holding them open.. just my $0.02 worth, hope it helps you.....Rich

Nah new heads were installed, I measured for new pushrods....Put them in.Shimmed rockers as needed.

Was mentioned to me I could have skipped a tooth or so on my timing chain..

Anyone here ever do that?

It idles too smooth to be a hung valve. We would also hear a thump out the exhaust or intake depending what valve was open too long. Its a timing issue. It runs great til you put a load on it.
We are now wondering if the timing chain is a issue and the cam sensor can't correct it enough when it goes to advance the timing.

it is possible the cam timing is off, but the way that cam gear and chain look on these motors, quite unlikely.

did you make squish on come coolant and damage up a rod did you.

nah I pulled the heads this time with no blown gasket..After repairing last time all was well...
Tomorrow it is getting looked at

Idles too smooth and quiet for that. Its a hardened plastic tensioner for the timing chain so anything is possible. Its possible on a hard launch or a downshift something might have slipped or cracked. We won't know until its inspected further. We replaced too many sensors and ran too many tests to ignore the chance of it happening.

Paul the tensioner assymbly itself is metal. It just has plastic/nylon slider on both sides of the chain, one on the tensioner.

Its possible for anything to happen. Allthough admittingly a bad timing chain would suck. Thats a full day job

I had the nylon tensioner piece break on me and timing stayed true...maybe if I kept driving it hard it would have skipped...not sure

You think its a full day job?? Intercooler tubes, radiator, crank pulleys and I would imagine just the water pump and you should be able to pull the timing cover off, line it up the best it could be and pull the gears.
Or just let Chris have the fun of doing the replacement and just drive the car instead of working on it.

Delayed reply? I've given up on my '91 SC too with it's starting issue, no matter what i tried it just sticks it's middle finger up at me and tells me to go **** myself.

Then add in the DIS on my '89 XR7 decided to pack it in because i Disconnected and reconnected the battery!!!

Hopefully with your other post you'll be able to figure it out being a possibly a Bad injector on yours..
