Well, I notice a big ass oil leak when I went to get my alignment done the other day. Looked to me like it was the cam to timing chain cover gaskets, the ones behind the cams. So before I started to take the whole timing chain apart, I figured I would just take the Ignition cover off. There was no oil on the top of the head at all, I put a q-tip around the cam area, where its recessed into the timing chain, nothing. I was like awesome, maybe it was something easy, but I knew for sure there was still a leak. So I look and look, though it was the cam to head gasket, nope, that was perfect. So then I jack the car up and look from underneath, what do you know right under the exhasut manifold, oil seaping out along the hole back of the head to block. Now my question is, why does this happen, and why no smoke out of my pipes from water, cause obviously the gasket is not sealing. This is a cometic gasket too, Do I have to tighten it back down after its running? Is this normal, will it go away?

1st, is the head the HIGHEST part of the motor there is oil? i have seen oil that seeps out of somewhere northbound from the head, and drip down and follow the head like that. I would suggest some oil dye and a uv light if you arent sure.
2nd. what head bolts/studs are you using?
Factory?
New Factory?
ARP?
that would determine the re-torque if any, but also the head gasket helps determine that as well.
Lastly, the head gasket, I have heard of problems with the 2.4, seems like lots of people like to drill the rivets out, and use copper sealant between the layers. I am not sure if the problems they are correcting with this, but something to research.
Also gasket related, was the block/head machined before install, was it done to the surface finish requirements of the cometic gaskets?
I had 2 Cometics in a row leak coolant between the layers. Even torqued them to Cometics specs (APR studs) and they both leaked within 200 miles. Drilled out rivets and used a crap load of copper spray (against Cometics advice) and never had a problem for another 16.5K miles. that was when I pulled the head due to some unrelated failure. I currently have a stock head gasket and if I rebuild again I will use a stock gasket again. Graphite FTW.
Me? I dont own an Eco and have no desire to. LD9 FTMFW
^Ha i like that LD9 4 ever....although I wouldnt mind learning a new engine. Check and see if you put the gaskets on right from the cam to the timing chain housing right. The timing chain housing has a hole where you put a bolt in to hold the cam gears so they wont turn when you are tighting them. well make sure those small round gaskets COVER those holes.
GMR has got nothing on this
I'll take my eco that has a 2 layer MLS from the aftory...
if needed I go lsj HG and get a 3 layer MLS...
