Seal the EGR valve connection cleanly with the Standard Ignition Exhaust Gas Recirculation (EGR) Valve Gasket VG163, a direct-fit replacement for the listed applications: the 1985-1989 Isuzu I-Mark and the 1985-1989 Isuzu Impulse. An EGR valve gasket forms the static seal between the EGR valve and its mounting flange, keeping recirculated exhaust gas contained at the joint so the valve can meter flow back into the intake without leaking.
- Sealing job: Seals the mating surface where the EGR valve bolts up, helping prevent leaks at the flange.
- Direct fit: Installs at the factory EGR valve location for the listed applications.
- Service part: A fresh gasket is designed to be fitted whenever the EGR valve is removed or replaced, since these gaskets are typically single-use.
- Signs it may need replacing: A hardened, cracked, or seeping gasket can allow a leak at the EGR joint; if a failed gasket is the cause of a leak or rough idle, this replaces it.
If exhaust or vacuum leakage at the EGR valve is diagnosed as the cause, replacing this gasket restores the seal.

Frequently Asked Questions
What does this EGR valve gasket do?
It forms the static seal between the EGR valve and its mounting flange, helping keep recirculated exhaust gas contained at the joint so the valve can meter flow without leaking.
Which vehicles does the VG163 fit?
It is a direct-fit replacement for the 1985-1989 Isuzu I-Mark and the 1985-1989 Isuzu Impulse. Check the Buyer's Guide tab to confirm fitment for your vehicle.
What numbers does this gasket interchange with?
It interchanges with EVG159, 2-25009 (225009), and 8943118480. Its own manufacturer part number is VG163.
When should I replace the EGR valve gasket?
Fit a new gasket whenever the EGR valve is removed or replaced, since these gaskets are typically single-use. A hardened or cracked gasket that is diagnosed as leaking should also be replaced.
Can a bad gasket cause a rough idle?
A leaking gasket at the EGR joint can contribute to a rough idle, but the symptom has other possible causes. Diagnose the source first; if this gasket is the cause, replacing it restores the seal.
