Hello,
I've started using my 2.5 N/A for motorway runs between Leeds and Ipswich and it's running really well (all apart from springing a few oil leaks which I'm on with fixing now). Anyways, the head gasket has started spewing oil everywhere again so I've taken the head off. The bores still look in good condition (a bit polished) but my new pistons are still in tact with no cracks etc.
1) Why does driving at higher speeds 60-70 seem to blow my head gasket? Technically there's no extra compression being created, it's just happening at a higher rate!
2) Should there be oil down the rocker shaft bolt holes?
3) If the head oil return pipe is blocked what will happen?
I'm planning on running this engine into the ground. I'm not too bothered about running at at high revs because it does perform well, doesn't over heat and pulls up hills on the motorway surprisingly well too. I just don't understand why my head gasket keeps popping!!!
Thanks for any help / suggestions
