It’s CRUNCH TIME!
Owner is picking up his classy 1985 Oldsmobile 98 in a few days, and I want to make sure it’s PERFECT before delivery.
We still have a few things left to address:
-Replace the Fuel Pressure Regulator and repair the leaky fuel line.
-Oil and Filter change
-Adjust the Ignition Timing to squeeze all the torque out of this silky-smooth Buick V6 engine 🙂
-Final Test Drive!
Hopefully the customer will be pleased with the results…
Happy Memorial Day!
Ivan

If you cut off the metal shroud on the metal end of that return line, you'll find its just a line with a hose nipple and you can just just use a line and hose clamp on it, no need to replace the metal end of that return line.
yeah, lots of readily made fuel line repair ends. you can typically get a whole repair kit with special end and a compression coupling (or barb fitting for nylon lines) at local parts stores.
DOH! at wrong size, GM was typically 3/8" for supply and 5/16" for return, with M16(3/8) and M14(5/16) threads, now they did vary around some over the years so always check first.
Admit it everyone wishes they had an Ivan within 100 miles from where they live, I know that I do.
Those 3.8 liter engines had an inherent imbalance shake at just above high idle speed. This was a known issue and part of the reason behind why the 3800 received a balance shaft when it came out for the 1988 model year. The 1984-87 3.8 engines all had the imbalance shake. Nothing to worry about and nothing can be done to correct it.
My family has been GM since before I was born. My Dad especially loved Oldsmobiles and owned several. He once gave me a 1962 Olds Dynamic 88 and I loved that car! I got a red 1966 Cutlass 442 for graduation, and it was amazing! Watching you work on this one sent me backa ways, Ivan! Thanks for the Memory Lane stroll!
I would almost bet that the lope at idle is caused by a dry plug in the cap.
Memorial Day
A day to remember those who gave their all so we can have it all!
It's a day to remember the soldiers who didn't make it.
The total Greatness of this video is hard to describe. These cars were great. A mix of pre-computer and computer. Saddest engine, VERY harmful to GM's rep, was the 4100 in the caddy. 1985 began the GM computer days. TELL THE OWNER that the OIL really matters. So too the Cooling system must be maintained…..Could easily go 300K with care. Also, get rid of the plugs. Install platinum plugs, Delco. Also, as to the EGR valve, well, some needed to be removed, and then the passage, Not the valve, snaked with a wiggling cable of steel in a hand drill, although the miles on this vehicle are so low, this might not matter. Love your old school timing light….I will Never part with the Sun unit that I have. The Timing absolutely matters of these GMs, even 2 degrees off hurts performance. At 100k miles, think about replacing the timing chain. Makes them run factory new…..
