ArdWrknTrk Posted February 7 Share Posted February 7 Really good idea on the high temp RTV with a block-off plate maybe :) Didn't realize the flare bolted into a NPT fitting. Good to know! Here is the eWissions diagram from this site. 😉. 😄 You can see 9d436 at the back, and the NPT to reverse flare adapters 390148s36 in the exhaust manifolds. ETA: 9c438 is a crush seal... HTH....

viven44 Posted February 7 Author Share Posted February 7 Cool! Easy peasy. I know very little about '70 Broncos other than mint ones are worth a fortune. 💸 Yes hoping it will be easy, the only downside is I will lose the oil cooler that the 460 was equipped with. The 460 should lead a more laid back life on the 78' Bronco so I don't think its strictly needed (hopefully!). Link to comment Share on other sites More sharing options...

I think he calls them " the hand grenade" Link to comment Share on other sites More sharing options...

Thanks a lot for the part numbers! 390148-S36 on a google search gave me an idea of exactly what i needed :) Edit: Saw an eBay ad, but here is a screenshot in case the ad is pulled. I assume this is what screws into the exhaust manifold eventually. Link to comment Share on other sites More sharing options...

viven44 Posted February 7 Author Share Posted February 7 The '90s oil coolers? I'll let Bill rant about those damn things! I think he calls them " the hand grenade" This is from an 86, so a small unit that bolts in front of the radiator, so I think there is no water to oil heat exchange. Pretty harmless but I don't think i'll need it (hopefully!) Link to comment Share on other sites More sharing options...

I've never seen an 86 oil cooler (factory) The aeronose trucks had an oddball oil to water right angle block adapter that would hemorrhage internally with (obvious) disastrous results.

There’s a good view on my parts truck with the grill gone. My 84 truck with the 460 also has the same unit from factory. The lines run to the block adapter and pretty stout and problem free.

But I did hear Bill mention that these were not such a problem. Link to comment Share on other sites More sharing options...
Gary Lewis Posted February 7 Share Posted February 7 I've never seen an 86 oil cooler (factory) The aeronose trucks had an oddball oil to water right angle block adapter that would hemorrhage internally with (obvious) disastrous results. I've seen Bill, and others, cuss and discuss the oil/water cooler, but apparently Ford wiped it from their collective memory as by 1994 the 1980 - 89 MPC showed this: Link to comment Share on other sites More sharing options...
