Engine:

Showing parts for every engine. Select an engine to see only what fits.

214 Engine parts are listed for the 1978 Honda Civic, in 47 part types, covering both the 1.2L L4 and the 1.5L L4. Each one has a brand, a manufacturer part number and notes that say where it fits.

The engine on the 1978 Honda Civic covers the internals and hard parts that build compression and keep oil where it belongs — gaskets, bearings, camshafts, lifters, seals and timing components. The largest groups are Piston Ring (16 parts), Crankshaft Seal (14 parts) and Camshaft Seal (13 parts). The other 44 part types cover the remaining 171 parts.

Buying Engine Parts for a 1978 Honda Civic

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 1978 Honda Civic?

Our catalog currently lists 214 engine parts for the 1978 Honda Civic across 47 subcategories and 44 brands, covering both the 1.2L L4 and the 1.5L L4. Each part is matched to the engine(s) it fits.

Do engine parts differ between 1978 Honda Civic engines?

Some do. 58 parts fit every engine; the other 156 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 1978 Honda Civic?

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 1978 Honda Civic 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 1978 Honda Civic?

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.
