Cheers for the reply. Yeah it was a huge pain and they only considered rebuilding it as it was with the repairable damaged parts, new bearings, no scoring on other sections etc. Anyway, i've moved on and glad it's going okay now. True, i'm glad it goes away and I guess would only be a valve...

Howdy all, Quick update from me, crazy how time flies! I had my injectors done at MTQ Brisbane, all compression results were great, from memory, 370, 370, 380, 400, 410, 370 or something like that, so all witihin 10% or so of each other so went ahead and did the GTurbo and PDI intercooler...

Howdy anyone that may still be in tune with this thread! 1988, 12HT, been running well the past 4 years i've had it, had the injectors overhauled 18 months ago with a reputable firm, never an out of touch noise until 2 months ago, randomly started tapping on top end around cylinder one, not...

Cool, thanks for the heads up. That info is great and those mods will have to be in the next round of upgrades when the piggy bank fills up again! I've got a 250K 5speed manual in mine but unsure of the engine's life. I'll see how it goes with the serviced injectors, IC and Turbo. Any idea what...

Cool, i've luckily saved enough to commit to the pair. Have you noticed much of a difference in performance or more peace of mind knowing the stock turbo can't explode on you?? Yeah very true. I've done similar tweaks when I put the boost T and EGT sensor in, upped the post boost fuel, (and...

Yes very true regarding the tear down, a bunch of indicators or obvious signs are good, but mostly only solid evidence is stripping and replacing for sure. Excuse my lack of knowledge, what's the ADS modified pump and H55? As it sounds it was running well (apart from oil use, which mine seems to...

Good to hear, I spoke to Cuan at GTurbo last week and by the end of the phone call i'd bought a Grunter and PDI intercooler, though I was mostly committed prior anyway, no sales pressure tactics and both are on their way. I've just received my compression test results (currently getting the...

🤤 🤤 🤤

Thanks guys, really appreciate the help. I'd love to do this process but making the call to do it right and do it once seems key. I've got it in to MTQ engines here in Brisbane for the injector servicing and had a compression test with all cylinders running well so at this stage i'll be leaving...

Thanks everyone and especially Mike for the very thorough breakdown of expectations and info, especially the point of out of round bores! As mentioned, i'd love to do this process but making the call to do it right and do it once seems key. I've just got it in to MTQ engines here in Brisbane for...

Hi guys, thanks so much for the advice, i'm taking it all on board and trying to navigate the best way forward. I appreciate you offering to help source too, as this is what I've found. I've called Engine Australia, their rebuild kit is $1770, then SMS Diesel, local branch is $1250 all genuine...

Hi all, awesome post and just was I was looking for haha. Seems it all went very well for you and i'm glad it's firing well, it'll love you for it i'm sure! I'm looking to replace pistons in my 12ht 390k with suspected blow by. It's the mechanics today for a compression test and will see what...

Hi all, I'm looking to do a partial rebuild (pistons only) of my 12ht 390k with suspected blow by. After researching the wear and tear of worn pistons and rings and potential damage caused, it seems Alfin insert pistons are the way to make the most impact to durability and may be possible for a...

Hi all, just picking up this awesome thread as i'm looking to replace pistons in my 12ht 390k and suspected blow by. It's the mechanics today for a compression test and will see what the results are. I would love to rebuild myself, (very handy with the tools and have done all other work to date)...

Awesome, thanks for the advice. After seeing MTQ engine systems mentioned in the Roothy Milo 2 rebuilds i'll be calling them Monday :D
