I like your lines being above the sway. But it's time for new tie-rods!

Here's a shot of my line run.

mine started rusting about 10 days after owning the car, now much you can do about it in the north east :shakes head:

Sand them down and spray with a high temp clear enamel.

I still have the same sound your describing.

I see that you also installed the upgraded power steering cooler from Stillin. I do also have the same cooler installed. I installed the oil cooler and the power steering cooler at the same time.
I got rid of the clicking sound that was coming from the sandwich plate by replacing it with the Mocal sandwich plate.

About the other sound. it's obvious that other engine oil cooled cars don't have the sound we have. my only novice explanation is the sound mite be normal and the bigger PS cooler just magnified the sound of the normal operation of the power steering, Or there mite be a stress on the Power steering it's self from the added cooler.

i think it sounds cool either way.

doesnt our cars take just under 6 qts of oil stock? So with an oil cooler I think you should be putting in another qt atleast depending on how big the cooler is. So are you sure the cooler is filled with oil? Maybe the plate isnt opening like it should. Modshack might be better able to add to this issue.

You're off by a quart. Stock takes just under 5 quarts. With a cooler you're closer to 6. I think I used about 5.5qts with mine which seems right visually.

Stock oil capacity is 5 1/8 quarts.

Any time I've done 5 1/8, I ended up having to siphon some out. Perhaps since I use the slightly smaller K&N filters.

Interesting. I use the HP1008 (the small one) and 5 1/8 is a perfect fill.

I have a 25R cooler, I think I ended up using 6.2 quarts

Which way did you install it (fittings up or down)? I have my fittings down. I wonder if I have an air-lock or the dipstick isn't accurate with that orientation. I asked Modshack about the orientation question and he thought it was a non-issue. With the fittings down, would the dipstick read 'full' and then the actual circulating level be too low when the system is pressurized and flowing (ie the cooler fully fills and the oil pan level is too low)?

Assuming the oil cooler is mounted higher than the oil pan the oil will run out of the cooler when the car is off, resulting in innaccurate dipstick readings, no?

What size is your cooler? With the lines and cooler only 5.5 quarts seems really low.

It's a 24 row Tru-Cool that Modshack used. It's hard to guestimate, but I wouldn't think the cooler is much taller than the oil level in the pan with the engine off. I had almost 6 quarts in there last night and I was above the H dot when pretty hot. I took off 300cc (~1/3 quart) and now it's just under the H dot when stone cold.

I just don't know any good way to check the oil level with the cooler installed to test the possibility of inaccurate dipsticks with the fittings down. I suppose I could unmount the cooler and hang it down by the ground. Then a dipstick reading should be accurate with the cooler full.
