The pickup tube o ring is the cheapest, most important part on my rover. They are also a pain in the *** to find and cost more for shipping than for the o ring.

I searched the forums and entire world wide Web and couldn't find an alternative so I got a micrometer at harbor freight and looked at the sole measurement (2cm) I could find online, and I took my pickup tube, micrometer, and 3 dollars to the auto parts store and here is the tested replacement:

Ten for 2 bucks plus tax. The outer diameter is 64/100ths oversize. Acceptable and makes a tight seal.

 

Nice find, Charlie!

 

You should write a book! I'll still wait for the movie

 

My movie would be a horror flick. I replaced the main bearings with the engine on the truck this weekend, after the conrod bearings last weekend, after the rockers, after the heads, after the lower intake, after the piston. Haha. It is like Friday the 13th every weekend! Sort of like the Revenant, which I made the mistake of watching last night. Or maybe Castaway...that genre (horrendous struggle, with final overcoming of obstacle/bad guy).

Stay tuned... That horror is going to end soon. CHEVY IN A ROVER. COMING TO THEATERS NEAR YOU. Or maybe just a decent, high compression, rover engine (Abran!).

 

You are a strange man

 

Great info, but I have just one question/concern. Wouldn't the O-ring need to be a specific rubber compound in order not to fall apart from the oil/heat?

I'd think any ordinary O-ring wouldn't be the proper rubber compound and it would crack, possibly melt, and fall apart causing a disaster.

I just know when I tried to use some ordinary O-Rings back in the day on my EAS system on my RR that they melted in the valve block assembly.... Causing me some grief to say the least.

 

True...


I have stories about gasket maker along with fuel line.

 

Found this.





O'Rings are made of Buna N material - 70 Durometer Nitrile Rubber

Resistant to mineral oil, hydraulic fluids, air, L.P. & natural gas.

With pressure, O'Ring stretches & flows filling seal cavity

At extremely low temperatures O'Ring becomes brittle, but still functions as a seal. Upon warming O'Ring will assume its flexible properties without harm.

Prolonged exposure to excessive heat will cause O'Ring to permanently harden.

O'Rings Measured By Inside Diameter & Thickness

Operating Temperature: -40°F to 275°F (-40°C to 135°C)

Available In Kits - #0001-O, #0003-O & #0004-O (Page 2)

Also Available in QT Clam Shell - Consult Price Sheet

 

I did throw one in the oven with my main pulley at 300 degrees and it was still pliable (and didn't melt). But I have not tested it with oil or solvents. I guess time will tell. I live to disassemble my engine, anyway (it seems).

 

Well?!
