Hi guys. Hope all is well. I have a question about an oil leak on my '95 945T (130k).

I pulled the lower engine cover and spent the afternoon washing the undercarriage, and cleaning all the spilled oil residue from the oil pan/transmission/under the turbo areas. I determined that my primary oil leak is coming from --- what I believe is an oil feed/returnline --- to/from my turbo. Right in front of the oil filter housing is the problem. There's a long tube that attaches to the block, and then attaches up to the turbo. I'm sure it's a faulty "O" ring. I think it seems to be leaking at this lower attach point at the block.

My question - and I'm looking at the FCP Groton site - do I need:
1) 947282 Turbo Oil Feed Line Gasket $0.30 Elring
2) 947621 Turbo Oil Feed Line Gasket $0.50 Elring
3) 1378680 Turbo Oil Line Gasket between return pipe and block $1.50 Genuine Volvo
4) 1306264 Turbo Oil Line O Ring Between Oil Drain Pipe and Block $2.50 MTC

And, since I'm there, I need to replace the coolant hoses that attach to the oil filter housing (oil cooler hoses?) These are definitely a bit soft from oil dripping on them. What are these called? I can't find them on the fcp groton Web site.

Thanks!
