![]() Fel-Pro Gaskets 1802 1957-1974 Small Block Chevy Oil Pan Gasket Set. This RTV is not to be used on the gasket face, but rather where the bottom corners of the gasket meet the end seals to fill the gap. Timing Cover Gasket, Composite, Small Block Chevy. Intake manifold gasket sets may contain a small tube of RTV. Only apply the sealant in the manner and locations directed. In cases where a sealant is needed for installation of a Fel-Pro gasket, a FIT® Form will be included, along with the proper sealant.In some cases the stretching approaches the bolts’ elastic limit, permanently stretching them. This stretches the bolts into their elastic range. Once they reach this zone they spring back to provide a precise level of clamping force. Also, RTV can extrude out when the gasket is compressed, and it could end up in an oil or coolant passage and restrict or block flow. T-T-Y head bolts are engineered to stretch within a controlled yield zone. Sealants can add thickness which creates uneven clamping force since the gasket will not be able to seat properly. RTV can act as a lubricant and cause the rubber gasket to slip out of place and split, creating an opportunity for leaks. The sealer can chemically attack the rubber sealing beads and degrade them.Using RTV on the gaskets with Fel-Pro's propreitary rubber or silicone sealing beads causes multiple issues: To ensure these technologies work in the way they were designed to, these intake manifold gaskets must be installed on a clean, dry surface with no additional sealants used. Fel-Pro's proprietary rubber resists all fluids and features multiple sealing beads that provide additional sealing and compensate for rough corroded gasket flange surfaces. They have an aluminized steel carrier that resists corrosion and is not susceptible to degradation from exposure to fuels, oils and coolants. PermaDryPlus intake manifold gaskets are designed to provide a permanent seal. $15/pair instead of $22 each.Intake manifold gaskets have been problematic leak areas for several years now. I would prefer Fel-Pro blue valve cover gaskets. I've used Timken and Fel-Pro repair sleeves recently. The existing damper will have a groove cut into it from the seal lip. You will almost certainly need a damper-hub repair sleeve. No need to buy it separately.ĭon't forget that you may need a new oil pan gasket as well, depending on what gasket is in there already, and what condition it's in. ![]() If you buy a new plastic front cover, the seal should be included. While you're in there, be sure to inspect the timing chain 'n' sprockets. If it were me, I'd buy a reputable front seal, install it in the existing plastic timing cover, put a thin skim of The Right Stuff on the existing elastomer "gasket" and bolt it all back together. Theoretically, the plastic timing cover is a "disposable, one-use" product. If anyone has any recommendations please post them up. My gut instinct is usually to stick to OEM ACDelco stuff when possible, but if there's anything that's a common knowledge upgrade (like the Fel-Pro Vortec intake manifold gaskets) I'd love to hear about it. Valve Cover Gaskets (X2) - ACDelco 10046089 Timing Cover Front Seal - ACDelco 10228655 Engine Gaskets, Marine, Top End, Chevy, 7.4L/454, Set. They include the seals not found in head sets, including replacements for the oil pan, water pump, timing cover, fuel pump, and rear main seals (depending on the set you order). Here's the list I've got picked out, all ACDelco stuff. Fel-Pro Performance marine gasket sets cover those situations. It's not leaking bad enough to bother me right now, but the next time it goes in for something I'd like to have the parts ready to go. ![]() All of the above are original equipment with about 150K miles on them. While it was in there I had my mechanic check out a couple of small engine oil leaks and the conclusion is that one of them is coming from the timing cover, and the other from one of the valve cover gaskets. So I had my '97 K1500 Suburban 5.7L/4L60E in the shop recently for an oil change.
