5 GT Turbo EFI - GT Turbo

A leakdown test will give you a better idea of ring/land/piston condition, if you don't fancy stripping it yet.

Saying that, the tapping noise could be a bent pushrod(s)/excessive valve clearance, and the smoke could be an unrelated turbo issue.

 

[Clarkey]

Or it could be shagged
Saying that, you could be right as always lol

 

[Mark Davis]

All valid but checked all push rods, in fact swapped 6 out of the 8 for newer straight ones. Valve clearances checked and rechecked and done no more than 15/20 miles ago.

I think I'll just strip down, doesn't take too long.

 

[Mark Davis]

In a kind of sick way I want it to be shagged so I can build it how I want. My choice of cam, timing etc etc.

 

[Clarkey]

doesn't take too long.

Haha, not with the amount of practice we get...............I do mine on auto pilot now

 

[Mark Davis]

Just as I thought, new engine time.

RIP C1J

Sucks to see that mate

 

[Adey]

wow, has something been through that?

 

[Mark Davis]

wow, has something been through that?

Nope, just a lot of det.

 

[Mark Davis]

What do you make of this ?

 

[Fordy]

silly question but how its the crank trigger on your car?

if its 36-1 on crank pulley, was the wheel welded to the pully and was the pulley welded to the crank shaft seal boss? if the wheel slipped a little that'll explain the death

Was welded to the pulley but not the shaft seal boss.

right before you do much more,
Get a dti gauge on the block and bring the piston on cyl 1 or 4 to tdc, have a look at the sensor and see if its still on the right tooth
i recon it might of slipped

 

[Fordy]

This is mine after it slipped once at Santa pod

 

[Mark Davis]

Good info Fordy, will do mate.

Been on to CTM who are going to sort head out for me and remove squish areas. Also elongate holes for better push rod clearance. Engine comes out Sunday. Components bought next week when pay day comes round and with any luck engine rebuilt in Jan.

What's the eta on the Pistons and rods? Mine took ages to arrive

They have them on the shelf by all accounts. That's standard comp ones, low comp are 2 month wait.

 

[Fordy]

Maybe it was because I had 77mm's

 

[Mark Davis]

Yeah quite possibly, 76mm ready to rock.

 

[Mark Davis]

What do you all think of number 4 wobbling all over the place?
