Hi mate and welcome could you pop over to the intros first before asking questions
just polite and all, no harm done just something the forum asks of us all
As for you problem did you know what your boost was at that time or what your EGTs were.

1 is bad enough but 2 man that's scary hope you get it sorted soon

Where did you get the 2nd motor from? Or was it a rebuild?

I think your intercooler was leaking creating low boost
which inturn gave you high EGts then bang 3+4 melt

Is your IC oily????

G'day and welcome to the forum. Recon you should be talking to whoever you got the second motor from.

Back again landy96 has started dementia so any help would be very apriciated so had trouble startingin site with password etc so intro location photo etc washard to work out .sorry for that. Cant find profile settings .
No gauges when 1st blew .yes intercooler is oily . 377ooo on clock .currently no reading on boost gauge ? 2nd motor was bare .told recond 25k kms ago .most of old motor parts refitted . Maf cleaned. Idled better with thingy underbellow maf disconected. So cleanedit to but doesnt idle better now.

Problem solved the guys at on track 4x4 slacks creek sorted me out . Stupid maf sensor made my car run like crap and the belt adjuster was bouncing around for hoffible sound . I bought a cheap one 2 months ago and it just died. Bought a dear one from autobarn but it doesnt feel any tighter ??? Thanks guys for the support and thanks ontrack 4x4 for great service ..cheers ..
