oil filter housing on 2003 Volkswagen Jetta

my oil was leaking and I took it into the mechanic. He did some re-sealing but said if continues to leak that it will need housing replacement. Is this something that I can find used or is it best to let him get the part for lots of $$?

I think that engine if it is like other 1.8 VW had an oil cooler between the oil filter and the engine block. I had seen and replaced the "O" ring between the cooler and engine on my own Golf and several customer cars.
Yes, leak was in btwn oil cooler pipe & oil filter housing. He re-secured bolt and resealed for a temporary fix.
In no way am I a mechanic but when he quoted me $500 for part and labour, I thought lemme have a look around. Everything I researched says the part is cheap so I guess for him to do the labour, that's where it becomes costly. I will try and get the part and have another mechanic do it for cheaper, I hope.

Thanks again!
