So we got to the root of the problem anyway, turns out a wrongly configured FPR led to the engine overfuelling and destroying the ringlands Costly lesson indeed and after some favours and a bit of saving the GT is back and running on the road Firstly, i got myself a full Toyota engine gasket set from Idrees and had every gasket and seal replaced and a new Toyota PCV valve as well.. Then we got the head sent off to be pressure tested, skimmed and fitted with new Toyota Valve stem oil seals. Came back like this: Things were going good but that was the end of the progress for a load of months due to a lack of funding! But another student loan came in, and went straight out again on the Starlet lol. The bottom-end was sent off to be rebuilt by Byre reconditioning. I got the block pressure tested.. bores honed and washed, ACL bearings and washers fitted, and pistons with new Toyota piston rings installed. Component list fitted: -ACL Big-end bearings -ACL Main bearings -ACL Thrust washers -Genuine Toyota piston rings -New timing belt & tensioner kit 4 cracking pistons from another Gt Turbo cleaned up and ready to be fitted with the Toyota rings The engine was torqued according to Toyota specs the head fitted with new Toyota head-bolts Just waiting on the paint to dry on the cam cover and in it goes!
