Revive a 2.7 after 20 years
After many years it is time to get it back on the road. What to do? I don't know why the car was parked. Family vehicle but most information died with the owner. 1976 2.7 original engine. About 78k miles. What is the checklist for the engine?
I assume the fuel system is shot. My concern is I see many bad things about the 2.7. How can I check to see why it was parked? In no particular order I will address plugs wires spark fluids filters exhaust check compression fuel-as stated above most importantly the radiator and antifreeze flush---------kidding Any advice would be appreciated Thanks |

Pull bottom valve covers and see if there is broken or pulled head studs would be my first thing to do on my list.

Leak down test would be up there...
Entire fuel system will need attention from tank to injector tip if it wasn’t stored dry.

Had the privlage of reviving a '76 after a 15yr storage. Found that the fuel residue in the pump and both lines (supply and return) had turned SOLID. Like rock candy. Good luck.

Welcome to the forum. Post some pics of the car when you get a chance.
I highly recommending doing a bunch of research and developing your checklist before doing anything. A 2.7 is already expensive to fix; a broken one more so. One suggestion I'll add is to do a very good visual inspection (go get a USB borescope if needed) of the cylinder internals, under the cooling shroud, in all the nooks/crannies, etc. I resurrected a '75 Targa and found numerous instances of rodent intrusion (chewed, leaky fuel lines, insulation removed from a primary battery cable, nest, dead baked-on rodent carcass, etc). |

78 sc
Here is what I had to d to get mine back on the road:
New fuel tank (orig one was so gummed up, would have had to cut it apart, clean it up and reweld. New tank was the economical choice New fuel pump Blew out fuel lines (with engine sides disconnected New fuel filter New accumulator (recently) Fuel dist was rebuilt Pop off valve installed Fuel injectors had a great pattern and flow rate so nothing more done on fuel system New air cleaner Plugs only had 65 miles so I left them. (I have since replaced) New cap and rotor New tires New brake lines and fluid New battery After getting it started, learned I had 8ish broken head studs so motor removed and tear apart begun. Great learning process I have put about 25xxx miles on her since then. Up to 33xxx miles now Good luck and post any and all questions here. (After searching first, of course). This is a great resource with amazing advice. |
