Product Details

Features

  • 1-piece aluminum cover seals the timing chain area, stops leaks
  • Includes "half" timing cover gasket, water pump gasket set, crank seal & bolts

Description

This 1-piece polished aluminum timing cover is built to replace a cracked, warped, or leaking factory timing cover on Chevy Small Block Gen I V8 engines and the GM 90° V6 4.3L (262 CID). The 1-piece design seals the timing chain area while giving the front of the engine a clean, finished appearance.

This kit includes a "half" timing cover gasket, water pump gasket set, crankshaft seal, and a bolt & washer set — a complete package for installation without sourcing those parts separately. This cover is built for long water pump applications only, and will not fit V6 engines equipped with a balance shaft. A thin front seal is required when used with some cast aluminum oil pans, and this cover may not fit as-is with cam button or roller camshafts — verify clearance before installation.


Applications
Fits Chevrolet Small Block V8 Gen I engines: 4.3L/262, 4.3L/265, 4.4L/267, 4.6L/283, 4.9L/302, 5.0L/305, 5.0L/307, 5.4L/327, 5.7L/350, and 6.6L/400 CID. Also fits GM 90° V6 4.3L/262 CID applications, except V6 engines equipped with a balance shaft. Long water pump configuration only. Common vehicle applications include Chevrolet Camaro/Nova/Chevelle, Chevrolet C10/C-K truck, Chevrolet Corvette/Monte Carlo/Impala, and other GM 90° V6-equipped applications where compatible.

Installation
Includes a "half" timing cover gasket, water pump gasket set, crankshaft seal, and bolt & washer set. A thin front seal is required with some cast aluminum oil pans. May not fit as-is with cam button or roller camshafts — verify clearance. Verify timing cover style, balancer clearance, and sensor provisions before installation.

Q&A

What's included in this timing cover kit?
A "half" timing cover gasket, water pump gasket set, crankshaft seal, and a bolt & washer set, along with the cover itself.

Does this fit a short or long water pump small block Chevy?
Long water pump only. Confirm your engine's water pump configuration before ordering.

Will this fit my 4.3L V6?
Only if it's not equipped with a balance shaft. Confirm your engine's configuration before ordering.

What's the difference between this and the version without gasket/hardware?
This kit includes a "half" timing cover gasket, water pump gasket set, crankshaft seal, and bolt & washer set. TSP's other version (SKU SP8420) includes only the crankshaft seal — useful if you already have the rest on hand.

Will this fit with a cam button or roller camshaft?
It may not fit as-is with cam button or roller camshafts — verify clearance before ordering.

Do I need a special seal if I have a cast aluminum oil pan?
Yes — a thin front seal is required when used with some cast aluminum oil pans.
