    JEGS Performance Products 50300 - JEGS Timing Covers Details


    This cast aluminum timing cover is designed to fit 1966-93 Ford cars and 1966-95 Ford trucks with 289, 302, 302HO and 351W engines, using either a standard or reverse rotation water pump. It has a universal fit for block or cover mounted dipsticks, "10", "11" and "2" o'clock bolt on timing pointer positions (timing pointer sold separately) and the provision for a mechanical fuel pump (block off plate for in-line pump sold separately). It includes timing cover seal and a plug for the cover when using a block mounted dipstick. This cover is ideal for race cars, show cars and street rods. Dress it up even more with a JEGS Billet Timing Pointer, part number 555-51280, for the "11" o'clock TDC location or 555-51281 for the "10" o'clock TDC location. Made in the USA

    Is the stock timing cover leaking or just plain worn?

    Don't search around for a used one when JEGS has new timing covers at a value price.

    Rated 5 out of 5 by from For use with Ford M-8501-E351S 'Shorty' Water Pump The Ford Racing ‘Shorty’ water pump is offered by Ford Motor Co for use on any Ford small-block when radiator clearance is a problem. It is approximately 2 inches shorter than the stock pump and requires special pulleys and alternator/compressor/PS pump mounts. (See Fig 1) It is not available at your local Ford dealer parts department but Jeg’s has them under their part number; 397-M-8501-E351S, $142.99. These pumps will work with either a clockwise or counter-clockwise rotation which means you can run a serpentine or a standard V belt accessory drive configuration. However, if you are trying to use the above mentioned Ford Racing ‘Shorty’ Water pump with your original Ford timing cover, or the recommended Ford Racing Timing Cover (pt No. M-6059-D351), then you’re almost certainly going to have coolant leaks. The following is how to fix that reliably and permanently. The problem is three-fold. First of all, the ‘Shorty’ water pump’s casting omits the bolt holes for the two innermost water pump to timing cover bolts. (See Fig 2) Second, the ‘Shorty’ pump does not mate properly with stock timing cover or the Ford Racing M-6059-D351 timing cover because neither of those timing cover castings has a ‘full-perimeter’ gasket surface to match the ‘Shorty’ Water Pump’s perimeter gasket face. (See Fig 3) And third, without the two innermost water pump bolts, the assembly is likely to leak coolant into the cavity formed between the timing cover and the backside of the water pump steel plate that goes between the pump and the cover. (See Fig 4) It should also be noted that coolant can leak into the small valleys on the top of the OE or FR timing cover over the timing chain. That’s because there is no bolt in these holes and if the OE Ford cover bolt holes have broken through the backside of the casting, it will leak at these points to create small puddles on the top of the cover casting. (See Fig 5) Jeg’s timing cover (pt No 555-50300) solves two of the three problems and the third can be solved with a small amount of Permatex Cold Weld (Pt No 14600) applied to the ‘Weep-Hole’ found at the bottom of the water pump gasket surface in the new Jeg’s timing cover (See Fig 6). We may not be able to keep coolant from getting in this cavity, but we can stop coolant from getting out. The Jeg’s cover does have a full perimeter water pump gasket flange to match the shorty pump’s full perimeter gasket face and, the two inboard water pump bolt holes are ‘blind-holes’. So, they can’t leak coolant into the top notches of the timing cover. Note; The Jeg’s 555-50300 Timing Cover does not have provisions for using the ‘Locator Sleeves’ at the lower corners of block/timing cover. To work around this, install timing cover as usual but leave all bolts loose. Then, install the balancer. This will center the cover about the balancer seal. Put your finger at the joint between the block oil pan gasket rail/Timing cover rail and position the timing cover for level, then snug the lower front cover bolt. Do the same with the other side and then tighten all your cover bolts. When ordering your new timing cover, get either a Fel-Pro Timing Cover Gskt set (pt No. TCS45168) or a Clevite Timing Cover Gskt set (pt No. JV856) if you’d rather have Dark colored gaskets. (See fig 6) Both are available at Jeg’s under these part numbers.
