    Oil pressure sensor 305 / 350

    Rcotner, you need the pressure sensor it looks like a bell of sorts. The sensors job is to send a signal to oil pressure gauge. The oil pressure (switch) has a couple jobs which I can’t remember at the moment. It’s located behind the distributor near the firewall. Hope this helped

    My Goodwrench is on life support. But what is the best course of action?

    This came out last night, for those of you not familiar with vice grip garage you should make yourself aquatinted. This is a good explanation of what to look for during the tear down phase of a rebuild

    My Goodwrench is on life support. But what is the best course of action?

    I think a healthy used sbc is a good option. Take it home and rebuild it ( rings, seals and bearings and swap her in. The way I feel about it is that if it’s a good motor it doesn’t need to be bored out, although heads are a different story they really should be cleaned up by a pro or replaced...

    Rear Main Seal

    If the leak got worse after he changed the intake I think that’s a big red flag. The front and rear rail on the sbc intake is notorious for leaking. Although, he’d have a nasty vacuum leak too and I think he would’ve mentioned that

    Wireing help please

    Remember that these trucks ( generally ) have an oil pressure sender and an oil pressure switch. The one wire with a black boot is the oil pressure switch it connects to the intake behind the distributor. The other wire I’m prettier sure is the to the choke

    Bolts holding power window to regulator miss matched

    I got one of these a few months back, great tool I wish I knew the existed before but hindsight is 20/20. Way better than nut and bolt and helps in tight spots for sure. I think I’ll use it when I do my window regulator...

    What have you done to your square lately??

    I installed some generic hood insulation from LMC today, it’s okay. Not perfect but pretty okay. It sure would have helped if they offered a template or if I had a spare hood. If anyone else is doing this I recommend at least 15 Christmas tree clips

    Custom Tail Lights or Not

    Iv never liked the Cadillac or corvette rear lights, even in the 90’s it had been dont to death. The el Camino look seems pretty clean and factory in my opinion. Although my vote is always for the factory look. I like boring

    Passenger side Coolant leak

    About 20 years ago I had built a very expensive engine for my Lincoln mk VII that had the oil pressure sensor give out on this very first road trip… that’s a quarter inch hole at 60 pounds pressure or so. That hurt the number eight cylinder and necessitated a bearings change.

    Passenger side Coolant leak

    Just an fyi. I rebuilt a 350 taken from a 1989 TBI and installed it in my 1985 pickup. When rebuilding the engine, I removed the knock sensor and observed what I thought to be a blind hole threaded in 1/4 x 18. I thought nothing of it for the past 18 months and maybe 3000 miles on the engine...

    gear ratio/rpm/crawl ratio calculator

    This is a great tool. It allowed me to play with rear gear ratios that complement my transmission shift points and my cams power band. Very cool

    Rough and shaking 350 after changing spark plugs

    The mystery isn’t solved but, I think Dave needs to start checking some things and get back to us.

    Rough and shaking 350 after changing spark plugs

    Rough and shaking 350 after changing spark plugs

    I’m still of the mindset that his problem is vacuum related. Why are others pointing toward wires? He said the problem happens when the truck warms up. Does heat or expansion complicate the ignition system? I’m genuinely asking

    Rough and shaking 350 after changing spark plugs

    I’m pretty sure that that brown thing with the 3 vacuum lines on the side of your air cleaner housing is part of your air temp setup. When is senses cold air it provides vacuum to the vacuum motor ( it’s just a door ) on your air intake that takes warm air off of your passenger side exhaust manifold

    Rough and shaking 350 after changing spark plugs

    Attached is a vacuum diagram for a 1985 305 it may be of some help. The pic is of the EFE / Distr , tvs (grey thermal vacuum switch on the waterneck) and the egr / purge TCC, TVS ( black thermal vacuum switch that goes right into the manifold water passage) These switches supply vacuum to...

    Rough and shaking 350 after changing spark plugs

    I don’t think this is your problem but it should be connected to your electric choke if you still have one
