Frequently asked questions

What is the AJ87773RBP crankcase breather valve for?
The AJ87773RBP crankcase breather valve controls ventilation flow in the breather system of the Jaguar V8 petrol engine. It regulates blow-by gases from the crankcase into the induction system, keeping crankcase pressure correct. This is the Britpart aftermarket version.
Which Jaguar models does this breather valve fit?
This breather valve fits the Jaguar S-TYPE X200 (1999-2008) with the AJ28/AJ33 V8, the XJ X308 (4.0/4.2L V8), and the XK8 X100 from VIN A30645. It serves the crankcase ventilation on these petrol V8 engines.
Why does a crankcase breather valve fail on the Jaguar V8?
Crankcase breather valves on the Jaguar V8 typically fail when the diaphragm hardens or the valve clogs with oil residue over time. That usually leads to oil leaks, rough idle, or raised oil use as crankcase pressure rises. Replacing it restores correct breather operation.
