    88 5.7L backfiring through TBI

    This started out as an intermittent SES light with the engine occasionally stumbling under acceleration. The only code was 12. Now, the engine back fires though the TBI and has little to no power. Fuel pressure is good. Plug wires are fine. Cap and rotor look good. Had a spare ignition...

    Replacing valves in TBI 350 heads

    The valve seals in my '88 350 were shot. The engine puffed blue smoke on cold start-up. I decided to pull the heads and replace the seals. The valves are all straight and the guides do not have significant play. I mic'd 'em and they appear to be ok. Some of the intake valves appear to have...

    Electric Cooling Fan Conversion

    I installed a condenser pusher fan last weekend. Used a 4 prong relay and connected the switched power line to the AC compressor clutch positive lead. Works great. Sent from my SM-G950U using Tapatalk

    Electric Cooling Fan Conversion

    I'd love to see a pic of that electric lawnmower.

    Electric Cooling Fan Conversion

    Hey man Thanks for the feedback. I already moved the sensor to lower radiator hose using the adapter mentioned in a previous comment. I was never really happy with the t-stat housing mount but it was the solution that worked. (thanks everyone for the feedback.) I found one plug available in...

    Refrigerant blowing out of AC compressor

    Condenser coil is new; only 3 months old. Air flow is better with the electric fans. However, I plan to put a helper fan on the condenser. I'll check the pressures on Sat in the middle of the day at 90 degrees. If its too high, I'll adjust it. Sent from my SM-G950U using Tapatalk

    Refrigerant blowing out of AC compressor

    Last night, I pulled the system apart and changed the orifice tube, A/C pressure valve and high pressure switch. Pulled a vacuum and recharged it with 40 oz. R134a and 150 PAG oil. Pressures were 40 / 250 @ 70 degrees. Temp at the vent was 40 degrees. It was frosty in the cab this morning...

    Refrigerant blowing out of AC compressor

    This is my week of weird stuff happening on the truck (88 C1500 5.7L). Saturday, the truck was idling in the driveway to test the new cooling fans and out of nowhere the compressor blew refrigerant out of the back. The entire AC system was replaced in May 2018. The pressures were set...

    Electric Cooling Fan Conversion

    I used 620-634 which is the same as the Four Seasons 76034. The local Autozone price matched to the Rockauto price of $134. Sent from my SM-G950U using Tapatalk

    Electric Cooling Fan Conversion

    That's an awesome idea. I hadn't thought about using an inline adapter. What size is the hose at the t-stat? 1.25" or 1.50"? Sent from my SM-G950U using Tapatalk

    Electric Cooling Fan Conversion

    I finally got tired of the noise and inefficiency of the mechanical fan on my 88 5.7L. The temp would rise sitting in Atlanta traffic. The clutch likely needed to be replaced but decided to switch to electric fans. This is my daily driver and it needs to be reliable. There are a number of...

    Thinner head gaskets on a 88 5.7L

    I plan to pull the heads on my 88 5.7L. They are original and need to be rebuilt. The valve seals are leaking. Rather than milling 0.10" off the heads to bump compression, I was thinking about using a thinner head gasket. The OEM replacement is 0.41" compressed. FelPro has a 0.25" gasket...

    A/c rebuild

    I did this in my 88 C1500 last month. System had been converted to R134 by PO but did not have pressure. Orifice tube had compressor debris in it. I bought the 4 Seasons compressor kit, condenser and hose set at Rockauto. Flushed the evaporator. I bought extra 150 PAG oil, emptied the PAG...

    Replaced intake gasket, now I get a loud ticking noise on cold start ups

    None that I have experienced. Done it a number of times. I did it this time due to the amount of sludge in the motor and the lack of use. The PO put 5K miles on it in 9 years. You can run Marvels Mystery Oil instead of ATF. I use the heavier weight oil to off set the lighter weight ATF...

    Replaced intake gasket, now I get a loud ticking noise on cold start ups

    I had the same problem. I changed the oil. Put in 4 quarts of 15W40 and 1 quart of ATF. I noticed a reduction in the lifter ticking after an hour of running. Ran the mixture for 1,000 miles and changed it to straight 15W40. The lifter ticking is hardly noticeable. The detergents in the ATF...
