Thread: Valve stem seals

there should be 16 valve stem seals... my recollection is that valve stem seals should be more like o-rings... could they be for the fuel injectors? Might be worth calling KarKraft and asking them to confirm the kit contents...

The early RRCs used umbrella seals on inlet only, but I have never seen "seals" like that.
If you are having the heads serviced , have the guides machined and fit proper teflon seals , which the later v8s had . You can put them only on inlet or both as the late 4.6 had.
It cuts down oil consumption a lot.

Early 3.5's and also P76 engines had no valve stem seals, and no provision for them. The washers splash away some of the oil running down the inlet valve stems. All stepped guides can use the later ERR1782 clip on seals that are blue in colour. If I build an engine for heavy service on LPG I leave off the exhaust seals, and only fit inlets, as this helps valve life. I have used Teflon seals once or twice but they leak too much oil IMHO. They are favoured for racers.

I can't remember where I got my last VRS kit (for a D1 3.9) from but it contained the blue clip on seals.

I also meant the blue seals with a spring around them, which I always have thought were called teflon seals.
Now I look the blue ones are Viton.

These anyway

Get some fuel injection hose that is a neat slip fit over the valve stems. Cut it to lengths that concertina as the valve opens. Works a treat. Old car dealer trick for smoky Valiant Hemis that were notorious for oil burning from worn guides.
