Hello! New to volvos and new to this site. I am hoping someone can help me with information. I bought an 05 s40 with 2.4 had a warped cyl head. Replaced head had machined. Got cyl head back on and torqued. Now before i go and place the cam cover i cant remember where the green o- ring went near the front side, timimg belt side and i also dont remember having seals on the rear side of cams.. The kit comes with 4 seals?? It has taken months to find a good cyl head and i didnt think i would forget this stuff, but i did! If you can help thank you!!!
