2.4 tdci 135 2004 exhaust cam tight?

Postby eddy dar » Sat Sep 22, 2018 3:05 pm

Ive started a new thread. But im in tge proceas of doing my cylinder head. And im using the cams that were on the orginal failed head. Ive tirqued everything up as per procwdure 23nm etc. But the exhaust cam whilst will rotate with the help of a rachet just seems to have a tight area. The inlet on the other can be turned by hand. The last head cracked the carriers on no 4 exhaust and from memory was tight then. Im wondering if tge cam is bent or not for this head.

Did cylinder head come with top part of cam carrier? These are machine matched and puting different top on can cause the problem you have

Cylinder head and frame form together holes for camshafts. Holes are machined with both parts put together and from this moment they make one part (inseparable set) with one number.
So: you'll be lucky if alien frame will fit cylinder head (concentric camshafts holes).
Look for picture - cylinder head and frame have been marked violet triangle (left upper picture corner) and appear on the list as one part with number 1701871.

However camshaft may be used old one or new one - it doesn't matter.

Try check which one hole is nonconcentric and use (very carefully) adjustable reamer. It isn't best solution. Best is very expensive - new set 1701871, no chance for used, good, trusted set from ebay.

You have to find out what's the issue with camshaft , otherwise it could heat up and seize up . Both camshafts should be able to turn by HAND with just a bit of force and should have a smooth and equal friction all around . Have a good look at the cam carrier with camshafts removed to see if there is a scored or broken surface on either carrier and camshafts . Unusual for the exhaust side to go wrong if timing chain jumped . It is mainly the inlet side that is mostly damaged .

To do it it's necessary take out cylinder head. Screw together head and frame without camshafts and check holes for exhaust camshaft:
- is it ledge on interface of two parts,
- are hole dimensions - horizontal and vertical the same.
Compare dimensions with inlet camshaft holes.
Somebody thinking can do it in amateur condition - you simply need good caliper... Problem can be with adjustable reamer - it is expensive tool.

-----------------------------

About twisted exhaust camshaft - lose frame as it will possible rotate camshaft, and check his chain wheel - is it keeping correct plane during rotate - isn't warped.

Yes exhaust is tight and has a sticking area. Inlet turns by hand everytime even force very nice. The timing was perfect just no 4 exhast carriers bith cracked. Ran rough smoky. What would cause this?

That small crack on carrier could have been caused by piston 4 hitting the exhaust valve or some broken ring bits inside the cylinder . Check the bolts that are holding down the carrier . If any of them feel loose or feel like thread not holding than is time for a new carrier .
Did you removed the head and checked cylinders and pistons for possible damage ?

What if cam lobes have moved or are cams different for a tddi & tdci.
