Buying Engine Parts for a 1987 Excalibur Phaeton
On this vehicle, the engine covers the internals and hard parts that build compression and keep oil where it belongs — gaskets, bearings, camshafts, lifters, seals and timing components.
- Match the engine first. Some engine parts fit every engine; others are engine-specific. Each row shows which engine(s) it fits.
- Read the notes on each row for position, trim and spec qualifiers before you order.
- Where labor overlaps, replace the seals and gaskets for anything you open up; a timing job should always include the tensioner and guides, not just the belt or chain.
- Cross-reference the manufacturer part number against your old part or a service-manual listing.

Frequently Asked Questions
How many engine parts fit the 1987 Excalibur Phaeton?
Our catalog currently lists 169 engine parts for the 1987 Excalibur Phaeton across 32 subcategories and 14 brands, covering both the 5.0L 305cid V8 and the 5.7L 350cid V8. Each part is matched to the engine(s) it fits.
Do engine parts differ between 1987 Excalibur Phaeton engines?
Some do. 91 parts fit every engine; the other 78 are engine-specific. Each row (and the filter at the top) shows which. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.
What are the signs of engine problems on a 1987 Excalibur Phaeton?
Common symptoms include oil spots under the vehicle, blue or white exhaust smoke, ticking from the valvetrain, or coolant mysteriously disappearing. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
What should I replace at the same time?
Where labor overlaps, replace the seals and gaskets for anything you open up; a timing job should always include the tensioner and guides, not just the belt or chain.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 1987 Excalibur Phaeton was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 1987 Excalibur Phaeton?
First match the engine — each row shows which engine(s) the part fits. Then engine hard parts are unforgiving of guesswork — confirm the casting or engine code before ordering, because one model year can hide two different blocks. The notes column carries position and trim qualifiers where they apply.
