k series head bolts wont tighten


Recommended Posts

Hi

 

wondering if any of you guys know what my problem is ?

I have just replaced the HG on a 1.8 k series 16 valve and after hand tightening the new head bolts, 2 of them wont tighten ???

They are 2 and 6 if your'e familiar with the tightening pattern. The other 8 all hand tighten no problem.

I know i'm probably gonna have to remove the sump and check the oil rail but just in acse anyone can help shed light on this

 

TIA

I've never worked on a K series but believe the bolts are a substantial part of the strength of the block, so if there's any chance that the thread at the bottom has failed, then pull it apart and check, but hopefully they just hadn't engaged thread properly.
