| Post subject: | possible new valve cover |
I have been checking around for valve cover option for my project and came across PML mfg. They appear to make a high quality sand cast valve cover. I would like to find out how much interest there is for a new valve product. I think a more basic one like MP sells for the v8 would sell well. Here is the response I got from the company when I e-mailed them. Thanks 69 dart Steve, If we felt like we could sell 50 a year it would be worth doing. We've invested in a couple valve covers in the past that have turned out to be poor sellers for us so the owner is justifiably wary. On the other hand, we make valve covers for the 500 Cad V8 and do okay with this one. How much commonality is there in the slant six family as far as valve covers are concerned? Do the 170, 198, and 225 all share the same gasket surface shape & bolt pattern? What years are involved? I know they used these engines in cars, trucks, and vans. What features would you want in a new valve cover? Height? Fins? Raised lettering (if so what would it say)? Do they all need a pcv location, breather, oil fill? Anything unusual about the stock design? (anything mount to it that we would have to accomodate etc) Does the interior need to be baffled or open? Regards, Brent Lottman (brent@pmli.com) PML, Inc.

I would think with the new milestone of 1000 members, we could find more than 50 customers. Heck - I'd be one of them. |

Black color would be cool. I think the valve cover should have hole for fill, breather and pcv. They should be baffled. Fin would be cool but not necessary. Overall great idea since clifford has cut back their offerings for slant 6s. |

Just wondering, i'm starting to mess with some carbon fiber, and am trying to make some carbon fiber valve covers for a 361 (b engine) i have. If i end up making some, would there be any interest in one for a slant 6? Nick |

If you could get ones made up like the Black Ribbed V8 Mopar ones it would be so cool. Like These: http://www.mopar.com/m_perf_parts_produ ... itemID=442 although Mopar might not like it to much.... If they couldn't get a release from Mopar, might just replace mopar with 225 or Slant 6. I think it should have a rear PCV grommet hole and front Breather Stack.... This way if you want a closed system you can put on the correct type of breather and your set... or if you don't you just put on a normal breather... if you go with the 3 hole approach first its going add more junk to the look, and people who cant use or don't want to use a closed type PCV system wouldn't be forced to have a goofy look sense there would be no where to put the hose. About Years... i'm almost positive the mounting surface is exactly the same from 60-91 when ever the /6 was taken out of production... i'm not 100% sure of the Alum blocks... but i'm pretty sure they are the same too sense they didn't use Alum for the head. As for the 225, 198 and 170 they all use the same head, so of corse the Valve covers are inter changable. As for attaching something to the valve cover, most or all the valve covers I seen have little tag things to hold wiring in place. Would be nice if it was a bit better looking. Also some years have a bracket to support heater hoses but I don't think you need this. Sense you don't have to have it... and if you wanted one it would be super easy to make some thing that attaches with the valve covers bolts to replace it. |

The finned design is nice, but instead of any cast-in names or logos, I would like to see a flat surface where you could place a decal or attach an engraved plate with your own design. A raised boss for attaching hose straps would also be great. Holes for installing the late model PCV valve and oil fill cap would be the logical choice, since those with restoration in mind would use the stock cover anyway. |

Quote: About Years... i'm almost positive the mounting surface is exactly the same from 60-91 when ever the /6 was taken out of production... I believe there were at least 2 valve cover designs: from introduction to about 1981 (the solid lifter engines) used a flat rectangular surface and from 81 on (hydraulic lifters) had a front corner that was rounded. I've not seen one of the newer style up close, and don't have my manual handy, but I believe this affects the mounting surface and gasket style. Anyone know for sure? I also don't know about marine or industrial applications, but how many would want a custom valve cover on their forklift?  MTSteve ps I'll take at least 1. |

| Post subject: | one cover fits all? |
Couldn't there be one valve cover design that would fit solid lifter and hydraulic motors alike? I think one like the V8 Mopar covers mentioned above with Slant Six cast in would be awesome! |

I followed up with PML a few days ago; here is the text of what I sent them: Quote: How much commonality is there in the slant six family as far as valve covers are concerned? Do the 170, 198, and 225 all share the same gasket surface shape & bolt pattern? What years are involved? I know they used these engines in cars, trucks, and vans.
All 1960 through 1980 slant-6s, of whatever displacement, have a common rocker cover bolt pattern (the stock steel covers varied somewhat in oil cap/breather/PCV detail, but they all interchange within this year range). The variant cover was the '81-up unit (hydraulic lifter engines). Just about nobody builds the '81-up heads for performance use, so no real point in creating a cover for the later head. A common (fits both) cover would not be practicable.Quote: What features would you want in a new valve cover? Height?
My vote would be "stock!" There are several applications in which the topof the rocker cover is a VERY tight fit to other engine bay items, particularly in some of the more popular cars for hotrodding ('60-'62 Valiant/Lancer comes to mind) and remember, these engines have solid lifters so the cover needs to come off periodically for lash adjustment. On the other hand, the full-boogie race guys (of whom there are fewer than the stock-valvegear "hop up" guys) may want extra height for some rocker setup of which I am not aware. To my knowledge, while there is at least one very-high-performance rocker setup available, I am fairly certain it is compatible with the stock rocker cover and therefore with stock height. Quote: Fins?
Never a bad-looking thing on an aluminum cover. It would be nice to be able to choose between paint *or* polish and get a nice polish on it.Quote: Raised lettering (if so what would it say)?
That is a much tougher question. My vote would be for no lettering,because anything you apply will narrow the interest (if you make it say "Dodge", the guys with Plymouths won't use it; if it says "225" the guys with 198s won't run them) or run afoul of trademark law (if it says "Mopar", DaimlerChrysler will come after you). Decals are easy enough these days to have made; perhaps an area reserved for end users' own decals would be apropos. Quote: Do they all need a pcv location, breather, oil fill?
Yep, definitely -- this is the big problem with the Offenhauser cover, isthe absence of proper internal baffling and the absence of anything but ONE oil cap chimney. One option is to have a standard twist-lock (cam-in) oil cap near the front, a larger hole (can get you the dimension) for the breather grommet and breather towards the middle, and a smaller hole (can get you this dimension, too, think it's 1") for the PCV valve grommet and PCV valve towards the rear. This would duplicate the '70-up stock cover's setup and would be compatible with the '60-'69 engines as well. Or, alternatively: A grommet at the rear for the PCV valve, and a cam-in/twist-lock at the front for a Ford-type combination oil fill/breather cap. I would need to refresh my recollection of the available caps to get more specific, and I'm away from my desk until 5/2, but if I recall correctly these caps can be had in types to suit both closed (ducted to air cleaner) and open (vented to atmosphere) ventillation systems. This option may well be preferable; it would leave a larger uninterrupted area of the top surface for fins, decals, etc. compared to a 3-hole setup. Quote: Anything unusual about the stock design? (anything mount to it that we would have to accomodate
There is a heater hose bracket; some provision for duplicating its function would be a good idea.Quote: Does the interior need to be baffled or open?
Baffled. A simple baffle under the breather cap, a simple baffle under thePCV valve. Care has to be taken to set the baffle height so that it does not interfere with the rocker arms at full valve lift. These baffles are much more necessary than most people realize -- without them, enough oil flies around in the top end that the PCV valve sucks them up (engine smokes) and the breather sucks them up (air filter gets wetted down with oil). |

One other idea to think about. Since we have to periodically adjust valves, a two-part cover might be an option. It would sure help with oil splash. Might be hard to design with the angle of the cover. |
