There is no oil pan gasket on an XL-7, and if you're referring to the engine oil pan, and you're not a mechanic, I would suggest you not attempt this one on your own.

Is your XL-7 4WD?

If it is, the front axle is under the oil pan and you will need to either drop the axle or lift the engine.

Another thing to be aware of - the oil pan rarely leaks, unless it has been disturbed - if you have what you feel is a leaking oil pan gasket, it is more likely to be oil leaking higher up and running down & back.

It's a 4WD. If not the oil pan, where else can the engine oil leak come from?

Oil obeys the laws of gravity, oil leaking from any joint above the oil pan will run down and appear to be a leaking oil pan gasket - a leaking rear main or crankshaft front seal, a loose oil filter, a leaking oil pressure switch, leaking valve covers, the list is endless, and so far, not specific to the Suzuki H27A engine that you have.

H series Suzuki engines also have their own quirks, there is an upper & lower oil pan, and a two piece block assembly with O rings between the two parts of the block and also between the block & the upper oil pan - whilst it would be unfair to describe these as known problems, they do give trouble if disturbed, as do the timing covers - in fact Suzuki has a TSB out on resealing these engines and warns that what may appear to be a leaking timing cover, is often oil leaking and running down.

What needs to be done is a thorough cleaning of the underside and then observation to find the source of the leak.

What's the best way to clean the underside to find the source of the leak?

Also this leak started after I took it to Pepboys to get the EGR valve replaced. What are the odds?

You'll need to get the car on a hoist - or at the very least - ramps, spray on degreaser and a garden hose. I would suggest not using a pressure washer, or if you do, don't go from above with the pressure washer - the electrical connectors are splash resistant but not waterproof.

Do you have diagrams that I can follow and use as a guide?
