Please help guys-my heads mixed up, long story but here goes.

bought me series 2, 2 years ago. Engine went completly. Had a full rebuild courtesy of PJ. In total off road for 5 months

then 6 months later car gets nicked and I reshell it. Car off road 3 months.

I drive it for like 6 weeks and bottom end goes due to oil pump.

I source a new low comp bottom end and after 3 weeks it goes on me. My so called mate, checks everything. He says its ok and after8 weeks i get it back. I did 4 miles and now its fooked.

do i rebuild bottom end for 350, buy a complete engine from breaker or just get rid?

This cart owes me like 6k now and i just dont know what to do. As you realise its now off the road again. I do have it booked in with the master PJ on 10th jan to see exactly wot is wrong.
