Hi team,

I’m dealing with an oil leak and suspect it may be a gummed up oil pressure relief valve/spring. Best I can tell, the pressure is blowing out the oil filter seal. I’ve replaced the oil cooler seals (twice in fact, just to make sure),the oil filter and there’s no leak around the oil pressure sensor line. No pushrod tube leaks either.

Are there pressure valve/kit replacements that are better than others, for a stock ‘73 2.0? Spirited street use.

I see an Empi kit and one from Tangerine Racing. Looking for opinions on products.

I'm still chasing weird pressures and leaks...

Is a gummed up oil relief valve a potential issue?

They “gum up” by sticking in the bore of the block and not sliding easily

Could happen
I’ve seen the stick in the other position with low pressure

The tangerine is excellent
I used the high pressure (I assume like empi) for 20 years plus
But would not go back from the tangerine style I use now

On some thread there was a comment about it being a potential cause, but I’m open to other ideas/causes. She always run at about 65 #s, idle or under load, which didn’t make sense. Then all of sudden I’ve a significant leak. Idling from cold, there’s no leak that I can detect. After about 10 minutes of idle, she starts to leak, significantly.

Absolutely open to your thoughts on other causes.

Just a few more days of driving weather left.

Were you checking that with a mechanical gauge? 65 pounds, idle or not, is definitely not right.

Yes sir, mechanical gauge and electronic, and they match. I’ve had the car for three years and it’s alway been that high. I didn’t know better until I’ve been trying to figure this out.

I’ve ordered the Tangerine Racing relief valve. If I’m lucky, It’ll solve it.
