Bad news
My 1293 n/a screamer is no more, just failed a compression test 170 on 1 and 4. 2 and 3 its tickling 30.

Third head gasket its taken out. between 2 and three.

Oh dear

Sounds like a good excuse to rebuild it with a turbo

i dont have the money for another head. stright cut drops, pistons and another cam.

boooooogger

Got A GTM With A Honda In the Back, and huge Nitrous bottle where the passenger seat should be when racing!

Yes. third head gasket. got the head skimmed and brought a new torque wrench. set up the mixture useing a exaust probe.

So i can only assume its terminal and rebuild into a diffrent block.

paint it red and ebay it!

then use the money to build a moderate turbo lump.

what gasket you using?

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

use a bk 450 gasket and torque the head to 55 ft pounds

more than likley if its Gone between 2&3
it will be pre ignition whats taken it out
check the timing

What CR was it before/after the skim?

In the 13's at last!.. Just

Have the block skimmed!

Just another couple of thoughts .....

Fuel:

What have you been running Sam ?

Are you using any fuel additives such as a combined anti valve seat wear/ octane booster with your unleaded, such as Castrol Valvemaster Plus ?

Using 95 RON unleaded as everyday fuel can cause pinking in a motor with a high CR, particularly when on the day it was set up the timing was spot on but the tank had 97 RON Super Unleaded in it.

Gaskets:

I've had great success with the dark greay fire ring / bonded in oil seal gasket (AF470 I think) with a torque of 55 lbft, an extra 5 lbft over standard.

Previous to this type of gasket, again with a great deal of success, I used an old trick passed to me by an aging Mini 7 racer. This involved placing a 2 inch piece of 5 Amp fuse wire between cylinders 2 & 3. This promotes greater clamping force to stop blow between the two exhaust valves. Could be worth a shot, but may not be entirely relevant with the latest fire-ring type gasket. Trouble is, its a lot of work to re-do if it dont work !

Minivanless, but reluctantly happy living with the decision. There'll be another one day.

The crowns of the pistons are cooked.
The rocker pedistals are cooked.
But water temp never went above 3/4.

Massivly too far advanced.

Edited because of angry statement at the end. Calmed down now.

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

I told them not to touch the bloody timing as that was done on the dyno!.

the original setup was fine i just wanted the fueling roughtly set on the hif44 i changed to from a 45.
