Re: Continental 520

I would go with fuel supply as Slidin Gator stated but I see you replaced your fuel pump, make sure your pickup tube is not fractured and sucking air. I would suggest running a good fuel pump with a regulator. I run about 7-8 PSI to my carbs with a Summit Racing Pump, similar to the Blue Holley Pump...

Re: Gso 480 operating temp

Mine will run 190-230 depending on how hard it is ran with a shroud, I read thru one of the lycoming articles and it suggests to run around 220 to burn off any moisture (condensation) which may have formed in the oil

Re: looking at a Igso480

Gary Barber@outlaw has the parts for the GSO480. I have a GSO 480 I agree they are a work horse, with the right prop and gear reduction mine is pretty good on fuel as long as I'm just cruising. If I lay into it with the twin Aircraft Carbs it will drink the fuel

Re: Need help GSO 480 oil issues

I never updated the post, it turns out I had three bad oil injectors in the cylinders free flowing oil off the main oil journal, ended up replacing bearings while I had it apart but they didn't seem bad. It appeared once the oil thinned it wouldn't open the bypass to the cooler thinning out the oil ...

Re: Gso-480 oil pressure problems

I had the same problem with mine, as the oil thinned I would lose pressure and the oil temp would raise. I pulled the motor to replace the rod bearings which weren't in bad shape so I replaced the mains as well. They were a little worn but not bad. What I did find where three out of the six Cylinder...

Re: cylinder Oil injectors on GSO-480

cylinder Oil injectors on GSO-480

Recently I have had a problem with my oil pressure dropping and temp going up once the engine get warm, several people have told me it might be a Rod bearing causing the problem. I decided to replace the rod bearings which were not to bad, and figured while it was apart to replace the mains which we...

Re: Big Trouble Brewing?

If there is pressure in the case unless you have a good locking oil dip stick, you would shoot the dipstick right out of the block, I had a blown 327 which blew the dip stick right out of the engine due to blow-by.

Re: Need help GSO 480 oil issues

Good news does not appear to be a Main Bearing or Rod bearing. I placed a oil pressure gauge on the back of the engine and received the same read as at the pump, as the pump pressure decrease so did the rear pressure which matched. Based on that I figure there is a bad bearing in the Gear Box on the...

Re: Need help GSO 480 oil issues

The funny thing is the CHT temperature is consistent 350-378 degrees never even reaching 400 degree's I do have a IR gun and forgot to bring it today. I'm leaning toward maybe a oil circulation issue or possible a ground / gauge issue. If it is an oil circulation issue not exactly sure where to look...

Kinda odd never have had an issue with the oil temp going over 180. this all occurred out of the blue with no warning after switching to electronic gauges, is it possible an oil ring might have broke causing the oil to heat?

My oil temp rapidly raises over 200 degrees on e it reaches 180. The only thing I did was switch gauges...

Faria makes a sending unit which bolts right onto where the cable would and you can utilize a electronic Marine Tach
