FAQ
Does this kit include the metal standpipes or dummy plugs?
No. This is a seal / O-ring kit for one bank. If you need updated hard parts (standpipes/dummy plugs), purchase those separately.
How many kits do I need?
One kit services one bank (one side). Use two kits to reseal both banks.
Will it fix hot-no-start or ICP leakdown?
If failed standpipe or front port plug seals are the leak source, yes—this kit addresses those seals. Always perform proper ICP leak testing before parts replacement.
Is it compatible with the 2004.5+ updates?
Yes—the contents cover both early and updated standpipe/front port plug designs.
