Ford 2L 8V DOHC Camshaft follower
Hi All
I have fitted new camshaft follower on my engine as the old ones were sticking . They have different sound now from before dose this mean they do need
to bed in I am afraid they are hydraulic no adjustment. Any ideas?

From my experience of doing head gaskets on these engines, the cam followers can be a MAJOR P.I.T.A. .
Firstly, I DO HOPE that you changed the Timing chains (and tensioners). Because at between 80K to 100K miles, the chains fail and when the chain comes
down from the top and gets whipped around the bottom pulley, the whip action (99% of the time) strikes the lip on the front main bearing cap and
writes the engine OFF (Front main caps NOT Available, or were not 20 years ago).
Then when you restart the engine, the hydraulic followers take time and oil pressure to refill. The FORD protocol for a restart was to start the
engine, THEN rev AND hold the REVs at between 2,000rpm and anywhere upto 4,000rpm for upto 4 hours for the followers to fill with oil and run
quietly.
This has proved to be the case with EVERY single one that I have done (ALSO make sure that all the chain guide bolts ARE TIGHT, one loose bolt on one
that I worked one droped down the the engine, with no damage, then bounced along the sump where it took off a random finger on the CPW, which stopped
the engine and blew the ECU {YEP it took out the ECU}.
I must have replaced 10 of these engines heads and EVERY single one of them sounded as though I had left something loose in the engine (the very first
one I, I was SURE I had left something loose and even rang Ford Technical for advice, they told me the 2,000rpm trick) did , then after mostly 2 hours
of 2,000rpm, they went quiet.
I hope this helps you.

Hi
Thanks for your reply it has been a nightmare . It was late night when I finished all the work then I started the engine it sounded great but I did
not rev the engine as you suggested. All the noise started the next day. since my post on the forum I had thought about the timing chain &
tensioner. I must say you have hit the nail right on the head.
As for the timing chain it had only done maybe about 10, 000 miles but I did fit the new tensioner which is oil filled. Do you think I should replace
both of them again?
Many thanks again.

I know that the tensioners aren't cheep (20 years ago they were £80) and are a use ONCE design, but, having worked on as many as I have, I
wouldn't take a chance on the chains (timing AND Oil Pump) and I would replace them. They used to be factory maked (different colour links at the
timing marks) for timing them up correctly, so relatively easy to fit, the biggest headache was carefully twatting the tensioner to release it (once
released you CAN NOT reset it, I tried).
the only other words of wisdom that I can pass on is that the head tends to develop cracks through into the water ways which also write the head off,
so look after the cooling system and don't ever let them over heat, IF it over presurises the cooling system, then the chances are that it's
a head problem rather than a a head gasket problem.
If you ever get the chance try using a 2.0 Duratec engine (16Valve), they tend to be less problematical, are lighter, can produce more power and are
not as tall as your engine.
