OK, need help figuring out where a couple of parts go.

First is this aluminum exhaust heat shield.  cant find in epc.

next,  the clip on clamp on the side of the power brake. what is is suppose to hold down?  I just put the fuel lines through it and they fit pretty well, but when I took the clip off originally there was nothing under it. 

The lower red circle, there was a yellow zinc clamp with a bolt hole on both ends to hold the fuel lines down.  dont remember if there was a rubber piece there or not, but I dont think so as the large protective tubing on the fuel lines would disallow them. the fuel line on the right is a new one and it didnt come with the protective sleeve like the old one.

Here is a picture of the underside of car with new undercoat. - 3m brand.  no problem with peeling. Wonder how long it will stay that nice color after driving?

Started engine today after all the work done to it and engine bay! with no exhaust on it sure sound healthy!

The heater control valve on firewall that I took from the parts car is leaking...it's one of the plastic ones. there was a water leak on top of water pump that hopefully sealed itself.   ;D

Can someone please post a photo of where the engine ground strap is suppose to attach to the chassis?  I cant seem to find any hole that would make a connection point.  for the time being I attached it to the idler arm bushing post as that was the only hole I could find that the strap reached, but I dont really think that is correct.

Got old bushing out of front lower control arms, waiting for parts,  and then will have to figure out how to get them in.

In the previous posted pictures I found where the extra heat shield goes, but could use confirmation about the clip on the master brake unit that I think holds the fuel lines.

I was hoping to drive it to a MBCA event next weekend, but looks like I may miss that chance.  :-\

Hey Robert yes that clip on the booster holds both the feed and return fuel hoses.

sooooo close.

Got front suspension completed, bled brakes, connected hydro pump line to regulator and fired it up. 

Huge leak from rebuilt hydro pump. I must of messed up the sealing o-ring.  At least the hydro light turned off rather quickly on the dash.

Next couple of days will pull the pump and see what I did wrong.


Wednesday we are headed to Wilsonville OR, to pick up our "new" 2014 CLS550!  Then a nice road trip back home.

Robert a good check for a rebuild is to block inlet and try and pull a vacuum into the feed side. If you cannot pull and hold 30 inHg of vacuum then you have a leaky pump.

took hydro pump apart and couldnt really find anything, perhaps a bit of dirt or there may have been a rub on the outer o-ring.  Anyway got that back in and is working fine now.

After tightening the drive shaft coupler nut I took the car out for a quick test run this morning. -  of course with no exhaust!

All I can say is "WOW"  what a difference the timing chain and valve adjust did. Went from rather ho-hum to a kick in the pants! If you recall  my right cam was 20 degrees off.

I was short radiator fluid so engine got hot so I took it easy back home and added over a gallon of fluid.  Now it appear my radiator leaks, or hopefully it was just the top hose clamp.  Will have to watch that one close.  Also small leak from one of the tranny pan bolts.  tightened a tiny bit, but I dont want to overtighten them either. This is the swapped in trans. 

Also no speedometer, that worked before.  If it is not just getting the shaft lined up what is involved in replacing what ever drives it in the tranny?



Trying to seal up various little leaks everywhere now.  I think the lid on the power steering pump leaks, lost a good bit of fluid from somewhere in that area.

Well, one step forward, one step back.  After spending 2.5 months working on my hydro pump, due to ordering incorrect parts, ordering parts and ordering parts again because I screwed up the 2nd order, then being on vacation for 3 weeks , I finally reassembled the pump  and put back on.  Good news that at least idle speed it does not  leak. I had got the car to rise and was checking again under the hood when the engine just stopped and I saw gas leaking from the main fuel line to the FD.  Discovered that the new rubber line I had a shop crimp on some time ago had just torn completely off at the crimp connection.

I recall him using SAE hose and fittings, they must be the wrong size as it completely tore the hose off.  Better sitting in the garage then out on the road though.

Well, off to source some metric materials.

Yes, they seem to have the materials, but who has the $1500 crimping tool?

I found a local mobile industrial hose service that may be able to tackle the project, they at least say they have metric hoses. Need to call them up and discuss.

Heh Rum,
sorry i missed your post.
this looks like the drivers side (thats RHS!!) shield on the firewall. you can see it pictured on my car with it on, with it off, and an example of its partner shield on the left side ( i dont have a pic of it on the RHS). flip it round and see if it fits!
regards

Actually I did figure it out, it screws onto the back end  of one of the under car shields.
