This table covers the oil filters that screw onto this engine's filter mount. Typical signs include low oil pressure after a service, or a filter that will not spin off because the old gasket stayed on the block.

Buying Engine Parts for a 1970 Lotus Seven
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. Every engine part here is 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 1970 Lotus Seven?
Our catalog currently lists 23 engine parts for the 1970 Lotus Seven across 3 subcategories and 12 brands, covering both the 1.3L L4 and the 1.6L L4. Each part is matched to the engine(s) it fits.
Do engine parts differ between 1970 Lotus Seven engines?
Yes. Every engine part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. 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 1970 Lotus Seven?
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 1970 Lotus Seven 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 1970 Lotus Seven?
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.
