Took the heap's engine apart today to reach the tappets... finally got down and took off the cam covers.

I took the lifters out to pump the clean as per MDTM's guide, I previously also had a go at doing a couple at his place.

I did not get along so well, i have a small vice borrowed from Jaime but i spent half the feking time keeping the vice still and level as its not mounted and as i close it, it slips.... also the handle to wind is less than a 3rd the size of the handle on MDTM's vice, so it proved very had to pump them clean.

I managed to pump it a few times, took it out, pushed with my thumb and it pumped ok, but then went rock hard. To get more leverage i attacked my jack and used the handle of that on the vice... but i think i must have gone too far, i managed to get more oil out of 2 of the lifters, along with flakes of brown crud. Problem is i think i crushed the lifters too much...  :-/ They feel a lot futher up than the ones i have not touched yet.  

I only have 3 replacement ones, i think, i have oppsed 2 of the old ones already, and this is on the good side, its the passenger side where the dud lifter is.

Picture before i took the cams out....

Are the older and newer type lifters interchangable?

If so, lets just shove 12 in there off my breaker (known good) - and stick the thing on fleabay pronto!!  

[TheBoy]

not sure if tunnies lifters are new or old type....

[JamesV6CDX]

Old... that's a 1995 engine!

[tunnie]

aye its old!!!

question for MrDTM - Lifters, are they interchange able?

You gave me 6, 3 of each type... could i put a full set of the later lifters in my pre 1997 engine?

As said, check with DTM

But personally, I can't see an immediate problem with using a complete set of one type of lifter in the engine,

But I'd want to confirm with Mark before popping them in...

I dont think they are interchangeable.
The later type seem to have been introduced at the same time as the higher capacity oil pump and the modified 'T' vents, these act as flow restrictors, the later ones have larger holes implying that the later followers are designed to work with a higher pressure in the cam oil gallery.

[Marks DTM Calib]

As stated, the later type work with the higher flow oil pump and the smaller T-vents so I would say......no they cant.

[Matchless]

Tunnie, I have some old type lifters you can have.
I have just tried to compress one and it was solid......I suspect that the old ones dont have a return spring so the usual flushing technique wont work. Ill work on another method.

[Matchless]

As stated, the later type work with the higher flow oil pump and the smaller T-vents so I would say......no they cant.

I thought the later T vent had larger holes......higher capacity pump can deliver more oil for a fixed pressure so doesnt need to restict the flow into the cam gallery so much. Hence the cam gallery will be at a higher pressure.

Yep, wrong way round....it was late and I was tired

Matchless and I have had a chat and we are going to carry ut a few tests on some of the earlier lifters and look to get a full set ready.

I ahev to say, the internals of that engine are 'worrying'...........did it used to belong to the coal board?

It is pretty manky, isn't it?

Little surprise that it's ended up with noisy lifters with the condition the oil must have been in to cause that much staining!

Definitely needs to be 'Sold as seen' ASAP!
