|
|
My 79 died a death a few weeks ago (valve stuck open, made nasty noises). It's been clacky & leaking oil for a while now & slowly losing power, so trying to figure out what to do next, would love to get some opinions from this group. It's a 2.0 with EFI, hydraulic lifters and I just spent $2k+ getting it through CA smog.
So my options that I'm considering:
1. Minimal repair - pull the engine, replace the head (maybe both)
2. Replace with a stock EFI
3. Replace with a twin carb (I'd prefer this, but not sure if this will pass CA Smog?)
Anyone else been through this? What would you suggest? And where would you recommend I get a replacement engine in CA (SF Bay Area)?
Thanks! |

1. No such thing. If it has a stuck open valve it likely has piston damage, maybe more. It is a full rebuild. Heads, piston and cylinder set, cam, lifters, bearings, etc..
2. Will have to be a stock FI bus to pass smog tests in CA. There are two configurations for 1979, California and Federal. The electronics don't interchange.
3. never can pass CA smog with a dual carb setup. Nationally it is an EPA violation too but most states have more things on their mind that to look around in engine bays. That said, if a state has remote sniffers looking for gross polluters, then that can be a different issue. A cat would clean it up in those circumstances but the mixture would be turning the cat cherry red until it failed. _________________ “Most people don’t know what they’re doing, and a lot of them are really good at it.” - George Carlin |

Check Bus Lab for engine builders in your area. You are likely going to want new AMC heads with the components upgraded. Whether you need new piston and such will have to be determined through careful examination after you tear the engine down. |

Bus lab is a place to try even though I’ve never had dealings with them. I’m thinking in your area they are probably the top choice. If you have a choice.
Please post some pics of your bus so we can see if fixing the engine is a good investment for you.
Sorry, if you were in Southern California I could offer more options _________________ Lead Mechanic: San Diego Air and Space Museum

Actually, here’s a thought. These days a lot of people are doing the Subaru mod. That means that the shops doing the mods may have complete T4 engines pulled from these buses. Some may be good, used engines. Maybe Skills would be able to comment on that _________________ Lead Mechanic: San Diego Air and Space Museum

Great idea! I had the same idea, and actually I just scored the 2.0 Type IV from the build Skills just started last week. So that one's gone! _________________ 1979 Mexico Beige Westy auto

Thanks for the advice everyone. She's starting to get rusty around the edges, but not ready to give up on her yet! I'll give Buslab a call and track down Skills.

Nice looking bus.
Instead of bothering skills, do your research and find other shops that do the Subaru mod. _________________ Lead Mechanic: San Diego Air and Space Museum

I’ve a type IV that was pulled three month ago for my Skillz conversion. It’s listed in the classifieds. |

Why do you think? Just curious… The 1700 and 1800 engines pass fine when stuck in late buses… KentPS did it and passed first try, but I think he also has matched early gearing. Looks like the pulled T4 had functional compression, but shipping may be the issues…
Just gussy it up with FI and all the evap bits…

I’m far from being a Jake Raby but first, there’s the smaller engine, then there’s the cam shaft. I thought a fuel injection engine used a different cam. Then there’s the exhaust system differences which might be a cat, 02 sensor, or EGR.
If it was me, I’d keep shopping for the right engine _________________ Lead Mechanic: San Diego Air and Space Museum

my vote, for what it’s worth, is stay stock.
call nate at broad street auto in san luis obispo (not too far away) and see if jonathan can get you a tuttle rebuild. _________________ 1978 Champaign Edition 2 Westfalia

The OP has a '79. That square port exhaust will not work on earlier heads.. If it weren't for that all other parts could be installed or adapted. _________________ 1978 Transporter 2.0 FI, BA6

1). Lots of square port engines have been retired already. Who knows what he has.
2). California smog creates issues when adapting non stock engines. _________________ Lead Mechanic: San Diego Air and Space Museum

the heat exchangers look like one is square port and one oval port. Don't know what is up with that. Might be a core engine.
The PO may need to spend a lot more than the $2K to get it thru CA smog just spent. My guess is that the engine will need to come apart and see what happened. The main difference mechanically between a 1979 CA/Federal and other 2L are the heads. Best practices would be to rebuild the existing engine with new Hoffman heads, or start collecting 2L parts to build a long block with new heads. The rest of the parts, tin etc should work. _________________ “Most people don’t know what they’re doing, and a lot of them are really good at it.” - George Carlin |

Stick with FI once you get to know them they are really simple, especially the early ones.
As to the stuck valve situation , replaces both heads if you are going for new, 4 new cylinders and pistons and both crankshaft seals.
Now as for determining if a full rebuild is nessasary , ask yourself was the engine bottom end solid before the failure, if yes then proceed by checking 4 things , con rod , con rod bearing and bush , piston pin , if none of these have no significant damage and the piston pin is not bent you just got lucky. Pull the hydraulic lifters one by one checking them and the cam lob for any sign of damage (remember to put them back to their original position) Next check maximum cam lift , those cams tend to wear way before the crankshaft bearings especially if low zddp engine oil was used . So make sure you have some decent lift or not she will need replacing , and that means splitting the case. Also check that the crankshaft turns smoothly. If you find nothing a miss then you could proceed but there is no guarantee on some hidden damage you didn't pick up. |
