V12 HE inlet valve part number help
#1
![Default](/forum/images/icons/icon1.gif)
Hi,
I have just purchased 2 new HE cylinder heads and Tappet block assemblies, plus a number of other new engine parts. In the box is a number of parts including some inlet valves made by AE (Federal Mogal). 8 in the box instead of 12, so I am looking to build up a set. The part numbers are V90304 and fit the valve seat and guide fine, but when I search on line for more I get conflicting info, some sites say the V90304 is for the H.E., but others say these are for the pre HE and I should use V90305? Can anyone confirm the V90304 is correct for the H.E. heads please?.
Thanks.

The pre HE valves are a different size from the HEs. [See below, this seems not to be true] If the valves you have fit, they should be correct. BUT, I do not know if the 6 litre valves were of a different overall length or valve diameter size from the 5.3 engines.
My real question is, where did you get the tappet blocks from, please?

The 6.0L valves are shorter than the 5.3L HE which is shorter than the pre-HE
When I bought new Intake valves the 6.0L are not available and the 5.3L ones are longer by about a mm.
Valve diameter are the same for ALL V12's pre-HE had a wider tolerance.
If the valves are not new I would check the stems for wear and roundness with a micrometer, every valve that came out of my 6.0L the stem was elliptical. So 24 new valves.

Therefore, does it matter as far as Clouder's original question goes, as long as the overall length of the valves is the same as the old ones (ie the new ones are not the shorter 6 litre valves)?

Further to the above, the Jaguar part number for PRE HE V12 inlet valves is EAC1549.
loads of places have them, (eg D Manners etc).
Manners list EAC3191 for the HE engine:

Greg, Warren,
I have now tracked down the AE web catalogue for valve components and discovered that their listing for the Jaguar 5.3 HE engine from 82 to 90 is V903004 and the OEM Jaguar part number as EAC1549............... as you say, that is the pre HE part number, not the HE part number!

I have bought one from Jaguar, and have asked SNGB to get me the other one, but have heard nothing back from them yet.
The Jaguar one has arrived, but the bearing caps appear to be un-numbered. How do you know which goes where? The caps are taped to the block in a line at one end, and I wondered if they fit in the order they are taped in. Can you help by any chance?

There are no numbers, but the bearings have been bored. This is a ready to fit part.

Hi Greg,
Sorry I meant to get back to you before this.
Each individual bearing cap will have a numeral (from 1 to 7) lightly stamped on the side of each bearing block in 5mm high numerals. Block number 1 is positioned at the front of the engine assembly and 7 at the back of the engine. If you look down onto the top of the bearing block, into the recess where the part number is, the small rectangular block with the manufacturers logo on, is positioned toward the front of the engine.
I have this information from what I see from the installations I have and not from any written data from Jaguar, so if anyone wishes to counter this explanation, please go ahead.
Thanks, Andy.

Thanks for your quick reply. I went out into the barn immediately after I read this and looked again. After about 5 minutes examining one cap very carefully with a bright torch, at last I found the numbers; feint, I should have seen them before but for some reason I could not! Must get the cataracts done!
Thanks again, I really appreciate it

They are numbered 1 from the front of the cam to 7 rear. On the A bank all the numbers are on the exhaust side but the logos on the top are not all the same way around. Same on the B bank except for number 6 cap which has the number on the inlet side.
The ONLY way to determine which way around the cap goes is to install them and torque each cap and turn the cam by hand, if the cap is the wrong way around the cam can not be turned by hand.
