aLmk's Turbo FA5

[aLmk]

Made some progress today:

The new chain, tensioner, and guides are in as well as the circuit hero timing chain guide as pictured above. It was kind of a pain to get the cams lined up correctly without the tool since it is on back order from honda.... This is as far as I got today, had to stop because I need to replace this o-ring and don't have the part:


I also noticed my intake cam has this mark across the whole thing:




Anyone know what that is? Should I be concerned?

Hopefully I can get the o-ring from the local dealership tomorrow and get this job finished so I can move on to the next.

I started removing my subframe yesterday in preparation for when my manifold arrives (hopefully end of this week, early next) and ran into some nuts/bolts that didn't want to break free - the ones that connect the LCA to the hub. Had to go buy a torch, but did get them free... The last time I dropped the subframe I did it different, dropping the hubs with the subframe since I only had hand tools at that time.

Once I got them off I noticed this:

The larger ones are from the driver's side, the smaller ones are from the passenger side...
Also one of the nuts on the driver's side took the impact a LONG time to take off even once it was broken free and basically off completely... It appeared as though it was cross threaded, or became cross threaded somehow. The threads on that stud and the nut are messed up. How hard is it to take that stud out? I already ordered new nuts last night when the couple nuts started to strip.

(best picture I could get of nut with phone camera)

Anyways, they are all off, now I can at least continue with the job.

Had some success tonight. Going to finish the actual timing chain job tomorrow:

Gl man and dbl triple check your timing before sealing it up

Spent the past 2 hours cleaning the block and chain case mating surfaces... Advice for anyone else doing this job with the motor in the car, clean the block mating surface before installing the new chain/guides/tensioner, it will give you a bit more room to work. From what I can tell I was still able to get it pretty damn clean using a razor blade and my finger nails




Also I think I got the timing as perfect as I can get it:

[monjarassi]

Yea u good.

[PetefromtheStreets]

Everything looks good and clean! Let's keep the good streak going!

Alright today I got the chain case back on I used enough honda bond for it to seal properly, I really don't want to do this again anytime soon. I also finished removing the subframe and got the manifold, downpipe, turbo, etc. out.

I also took some up close pictures of the manifold, maybe now you will see why I think it is the culprit for boost creep:



It is only grabbing off one runner, not even the whole runner, and it the exhaust has to make a greater than 90* turn to go out the wastegate.
Compare that to this:

Unfortunately, I do not have any other pictures of the manifold as I haven't received it yet.

Looks sick dude. Thats a huge dump. Lol
